FULLY WELDED HKSF-W 100
RMA-ball valves type HKSF-W are fully welded and completely maintenance-free designed.

TRUNNION MOUNTED HKSF-W 100
RMA-ball valves are
trunnion mounted
with maintenance-free bearings in all sizes (DN 50 and greater) and all pressure ratings
The precision machining and special low friction bearings ensure minimum wear.
These low torque levels are also an advantage when dimension gears, electrical, pneumatic or hydraulicactuators.

The Anti-Blow-Out- design prevents the spindle from being blown out by te medium transported or pulled out by the userhimself.
The special double-screw design enables, on the one hand, correct squeezing or adjustment of the steel, PTFE andgraphite sealing system manufactured by RMA and, on the other hand, rapid replacement of sealing rings under fulloperating pressure

Ideal material combination for metal to metal sealing
(passed successfuly the RUHRGAS Test)
The sealing system is primarily metallically, secondarily softly
The soft sealing is located flexible in the seating ring chamber. This ensures a primary active metallic sealing.
In case of wear, the soft sealing can readjust itself
It is pressed on by the o-ring and by the line pressure

DOUBLE PISTON HKSF-W 100
In the double piston-system the seals and seating rings on the inlet and outlet side provide total sealing of the body innerchamber in both end positions of the ball valve.
The ball valve provides sealing on the inlet and outlet sides. In this way, it is also possible to provide proof of sealing bypressurisation from outside the body.
We recommend the double piston-system for all gaseous media. This system offers protection in two respects to the user.

SINGLE PISTON HKSF-W 100
In the single piston-system the sealing ring on the outlet side raises when a pre-defined overpressure is presentinside the valve body allowing this excess pressure to escape to the outlet side.
The lack of pressure within the body provides proof of sealing.
We recommend the single piston-system for all liquid media.
This system prevents damage to the body caused by excessive overpressure through thermal expansion. In this
way, additional external pressure-relieve is not necessary.

DOUBLE BLOCK AND BLEED HKSF-W 100
Proof of sealing is provided in both end positions, even under maximum operating pressure of the ball valve, usinga special, self-protected nipple or, if required, using drain and vent pipes with an additional ball valve.
