- The design and manufacture of "CRH" high pressure ball valves is carried out considering extreme operating requirements.
- The ball seats between two pre-compressed gaskets with floating system, ensuring a perfect tight both at low pressure and under vacuum.
- With the increase of internal pressure a greater contact is obtained between bass and gaskets, permitting a perfect tight even at the highest pressure.
Technical features
- Full-way valve.
- Floating ball-gas light on pre-compressed seats
- Operating pressure from 320 to 500 bar (according to Ø)
- Operating temperature from - 20°C to 100°C
- Open at 1 /4 turn
Standard execution
- Body and connection : black phosphating steel (38SMnPb10)
- Ball : Thick-chromed steel
- Ball seats : polyacetalic resin (DELRIN)
- Pin seals : NBR
- Throttle lever : printed and zinc-plated forged.
On request
- Body and connection: yellow zinc-plated steel
