ANGLE VALVE

image of ANGLE VALVE

CAGE GUIDED TYPE

The PROVAL cage balanced control valves are designed for heavy duty service.

The valves plug is of a pressure-balanced type that permits flow control of a high differential pressure with bellows seal, extension, fin, jacket bonnet.

Standard actuators are multi-spring diaphragm actuator.

FEATURES

  • · More flow capacity for initial investment. Streamlined flow passages provide greater capacities than
    most globe bodies of the same line size. Balanced valve plug construction permits use of smaller, lower-cost actuators.
    Also, trim inventory costs are cut because dimensional standardization permits use of most standard
    PROVAL valve cage trim parts.
  • · High-pressure and temperature capability with class IV shut off.
    RTFE piston ring and high-seals permits. This shut off upto 230°C.
· Operational economy
Increased wear resistance of standard hardened stainless steel trim means long lasting service.
· Maintenance economy
The body can stay in the pipeline during removal of trim parts for inspection or maintenance.
