VALVES

Metal-Seated Ball ValvesANSI 150 to 4500

The thermal flood method of enhanced oil recovery is an extremely harsh environment forprocess equipment. In these economically and environmentally sensitive applications, the effi-cient use of steam is the key to keeping production or “lifting” costs very low. Valves and chokesused in these applications must be maintenance-free and should operate with zero emissions tothe atmosphere. For economic and for safety reasons, isolation valves should be zero leakage.Valvtechnologies offers a series of products designed specifically for thermal flood applications.

The Valvtechnologies metal-seated ball valve is designed to provide zero-leakage isola-tion for steam injection and production applications. The rugged, maintenance-free designfeatures an integral seat and a one-piece, blowout proof stem. Rocket Applied Metallic(RAM®) coatings on the ball and integral seat provide long-term wear resistance as well asprotection from the erosive characteristics of high-pressure, saturated steam. Live-loadedgland packing and an innovative body seal design eliminate external leakage.Valvtechnologies ball valves are available in sizes 1/4” to 36”, and in a variety of materials andend connections. Valvtechnologies valves used in steam isolation applications are guaranteedto be zero leakage and zero emissions for four years.

***Ball Material is Inconel 7-18 for class 3500# and 4500# valves

Testing Procedure: As a standard, all valves are seat leak tested with 50-psi of air for 3 minutes with the minimumacceptable passing criteria, being zero bubbles during the 3-minute test. This test exceeds ANSI B16.104/FCI 70-2 ClassVI leakage standards. Additionally a 1000-psi nitrogen seat test is performed for 3 minutes with zero bubbles. Furthermore,3500/4500 ASME/ANSI Class valves are seat leak tested at 4000-psi of nitrogen for 3 minutes with zero bubbles. Contactfactory for flanged dimensions.

XACTROLSevere Service Control Valve

ANSI 150-45001/2” - 36”

The Xactrol® product group unites Valvtechnologies’ zero-leakage technology

with special designs that allow rotary modulating control. From Mark I design

that features a characterized upstream seat, to the Mark III’s precision

engineered stacked discs, the Xactrol® allows the customer to combine precise

flow control with tight shutoff. The Xactrol® is typically used in applications

where minimum flow and relatively high differential pressures are required. It is

available in sizes from 1/2" to 36" and in pressure classes ANSI 150 to 4500.

COMMON CONFIGURATIONS

STEAMCHOKE

Steam Choke ValvesThe Valvtechnologies steam choke is designed for the harsh conditions associated

with steam injection. The rugged, maintenance-free steam choke features a self-

adjusting, double live-loaded design.

The stem/fork packing is isolated from the bonnet seal arrangement and is live-loaded.

Belleville springs on the packing gland bolts self-adjust to maintain constant packing load

regardless of thermal cycling. This design reduces the potential for packing leaks.

Valvtechnologies offers a four year zero emissions guarantee for steam chokes. *

STEAM CHOKE

5

The packing & seals on

the Valvtechnologies

Steam Choke Valve

will never require

field adjustment.*

The bonnet seal and the stem/fork

packing seal consist of a single layer of

Grafoil® encapsulated by stainless steel

wire mesh. Under a live load, this

packing design prevents costly and

environmentally sensitive emissions.

Belleville springs accommodate for thermal

expansion of the choke’s internal components.

During thermal cycling in startup or normal opera-

tion, the Belleville springs self-adjust to maintain an

ideal contact load between the control discs. This

self-adjustment eliminates the possibility of lockup--

regardless of process temperature or pressure (within

the material limits). The internal springs also provide

a constant load to prevent external leakage through

the bonnet packing.

The control discs are designed to provide precise

control so that production rates are controlled with a

high degree of accuracy. The discs also provide long-

term erosion resistance in high-velocity, saturated

steam service. Various orifice shapes, sizes and config-

urations are available for a wide range of production

rates and control requirements. The steam choke can

easily be retrofitted with new discs if well conditions or

production rates change over time.

* Guarantee valid only if the Valvtechnologies, Inc. installation and operations procedures are followed.
