A Tradition of Excellence

With the development of the first rubber seated butter-fly valve more than 70 years ago, the Henry PrattCompany became a trusted name in the flow controlindustry, setting the standard for product quality andcustomer service. Today Pratt provides the followingrange of superior products to the water, wastewaterand power generation industries.

A Commitment to MeetingThe Customers’ Needs

Henry Pratt valves represent a long-term commitmentto both the customer and to a tradition of productexcellence. This commitment is evident in the numberof innovations we have brought to the industries weserve. In fact, the Henry Pratt Company was the firstto introduce many of the flow control products in usetoday, including the first rubber seated butterfly valve,one of the first nuclear N-Stamp valves, and thebonded seat butterfly valve.

Innovative ProductsFor Unique Applications

Though many of the standard valves we produce areused in water filtration and distribution applications,Pratt has built a reputation on the ability to developspecialized products that help customers to meet theirindividual operational challenges.

Creative Engineeringfor Fluid Systems

Pratt’s ability to provide practical solutions to complexissues is demonstrated by the following case histories.

Earthquake Proof Valves

Pratt designed and manufactured hydraulically actu-ated valves for a water storage application so that thevalves would automatically operate in the event ofearthquakes. This lead to the development of a valvethat will withstand forces of up to 6g’s.

Custom Actuation/Isolation Valves

Pratt designed and manufactured valves that wouldisolate a working chamber in the event of a nuclearemergency during the decommissioning of armednuclear warheads. The valves were able to close in amillisecond using specially designed Pratt electro-pneumatic actuators.

Valves Designed forHarsh Environments

Pratt designed and manufactured a 144" diameterbutterfly valve for the emergency cooling system ata jet engine test facility. The valve was designed tosupply water to help dissipate the tremendous heatgenerated by the engines during testing.

Through experience, commitment and creative engineering, Pratt is uniquelysuited to provide superior products for our customers’ special needs.

Valves for the 21st Century page 2

DESIGN DETAILS: MODELS 2FII AND MKIISelf Adjusting Permanent PackingChevron type packing increases sealing force asline pressure increases. The self adjusting pack-ing bears on turned, ground and polished stain-less steel, minimizing wear and assuring long life.Packing is accessible for replacement withoutdismantling the valve per AWWA Standard C504.

Lifetime BearingsPratt’s chemically inert nylon bearings are sizedto meet or exceed AWWA specification pressureloads. They are self-lubricating, require no peri-odic maintenance and are designed to outlast thelife of the pipeline.

Corrosion Resistant ShaftsThe shafts in Pratt’s rubber seated butterflyvalves, 3” through 20”, are constructed of center-less, ground ASTM A276 type 304 or type 316stainless steel bar and thus are not susceptible tocorrosion as are carbon steel or other similarmaterials. Shafts are one-piece, through-shaftconstruction, sized to meet or exceed the require-ments of AWWA Standard C504 for Class 150Bbutterfly valves.

Streamlined DiscsPratt’s lens-shaped discs are designed to mini-mize pressure drop and turbulence. In the fullopen position, the disc creates no more frictionloss than a 45˚ elbow. Discs are secured toshafts by stainless steel pins to transmit requiredtorques and withstand stresses imposed under avariety of operating conditions.

Body SeatOur standard seats are constructed of Buna Nrubber and bonded to the valve body in Pratt’smanufacturing facility using a unique thermal pro-cess. This molding process ensures that thedisc-to-seat interference will not cause excessivewear or abrasion under normal operating condi-tions. On the wafer type MKII bodies, the rubberseat covers the entire inner surface plus the out-side face of the valve body to provide a self-gas-keting feature. Pratt’s seat-in-body designminimizes the effects of corrosive buildup on theinside of the valve because deposits are sweptaway by the hard sealing edge of the disc eachtime the valve is exercised.

Heavy Duty BodiesBoth Monoflange MKII and Model 2FII bodies areheavy duty cast iron. Model 2FII flanges are fullyfaced and drilled in accordance with ANSI B16.1,Class 125 standard for cast iron flanges.Monoflange MKII bodies incorporate an overlap-ping seat which also forms a gasket for the flangeface. The actuator mounting trunnion is ma-chined and drilled for a 4-bolt connection.

FEATURES AND BENEFITSOF PRATT MODELS 2FII AND MKII

FEATURE BENEFITSeat-in-body design - Reduces seat failure due to corrosive buildup in Seat molded in recessed body cavity, the valve and pipeline. No hardware to loosen. protected by metal on 3 sides No periodic maintenance required. Rubber protected

from flow media to increase seat life.

Valve withstood proof-of-design testing - Proven reliability over the life of the valveof 100,000 cycles - AWWA only requires 10,000 cycle proof-of-design testing

Through-disc pinning - Provides a tight disc-to-shaft pin connection,greatly reducing the possibility of looseningthrough vibration

Symmetrical lens-shaped disc - Higher Cv : lower head loss results in energysavings for customer’s system

Nonmetallic bearings - Prevents galvanic corrosion and provides lowercoefficient of friction

Chevron V-type packing - Self-adjusting, lasts the life of the valve

SUGGESTED SPECIFICATION FOR THE PRATTRUBBER SEATED BUTTERFLY VALVE, SIZES 3 THROUGH 20 INCHES

General Butterfly valves shall be manufactured in accordance with thelatest revision of AWWA C504, Class 150B and conform toNSF Standard 61. The manufacturer shall have producedAWWA butterfly valves for a minimum of five years. All valvesshall be either Henry Pratt Model 2FII or Monoflange MKII andcomply with the following details.

Valve BodiesValve bodies shall be constructed of ASTM A126, Class B castiron for flanged valves or ASTM A48, Class 40 for wafer style.Flanged valves shall be fully faced and drilled in accordancewith ANSI Standard B16.1, Class 125.

Valve SeatsRubber body seats shall be of one piece construction, simul-taneously molded and bonded into a recessed cavity in thevalve body. Seats may not be located on the disc or beretained by segments and/or screws. For wafer style valves,the seat shall cover the entire inner surface of the valve bodyand extend over the outside face of the valve body to form aflange gasket.

Valve BearingsValve bearings shall be of a self-lubricating, nonmetallic mate-rial to effectively isolate the disc-shaft assembly from the valvebody. Metal-to-metal thrust bearings in the flow stream are notallowed.

Valve DiscThe disc shall be a lens-shaped design to afford minimal pres-sure drop and line turbulence. Materials of construction shallbe:• ASTM A126, Class B cast iron disc with a stainless steel

type 316 edge

Discs shall be retained by stainless steel pins which extendsthrough the full diameter of the shaft to withstand the specifiedline pressure up to valve rating and the torque required tooperate the valve. Disc stops located in the flow stream arenot allowed.

Valve ShaftsValve shafts shall be of stainless steel type 304. At the opera-tor end of the valve shaft, a packing gland utilizing “V” typechevron packing shall be utilized. “O” ring and “U” cup pack-ing is not allowed.

PaintingAll surfaces of the valve interior shall be clean, dry and freefrom grease before painting. The valve surfaces except fordisc edge, rubber seat and finished portions shall be evenlycoated with asphalt varnish in accordance with Federal Spec-ification TT-C-494 and AWWA Standard C504. The exteriorvalve surfaces and actuator shall be evenly coated with a suit-able primer to match field coatings.

TestingHydrostatic and seat leakage tests shall be conducted in strictaccordance with AWWA Standard C504.

Proof of DesignThe manufacturer furnishing valves under the specificationshall be prepared to provide Proof of Design Test reports toillustrate that the valves supplied meet the design require-ments of AWWA C504.

Manual Actuators: Manual actuators shall be of the travelingnut, self-locking type and shall be designed to hold the valvein any intermediate position between fully open and fullyclosed without creeping or fluttering. Actuators shall beequipped with mechanical stop-limiting devices to preventovertravel of the disc in the open and closed positions. Actua-tors shall be fully enclosed and designed to produce the spec-ified torque with a maximum pull of 80 lb. on the handwheel orchainwheel. Actuator components shall withstand an input of450 Ft. Lbs. at extreme operator position without damage.Manual actuators shall conform to AWWA C504 and shall bePratt MDT or an approved equal.
