Key Features
- Factory testing of every valve at full rating ensures 100% tight shut-off.
- Actuator flange is standardized for easy operator interchangeability and direct mounting of Keystone range of actuators.
- Primary seal is formed by preloaded contact between disc and seat. These seals protect valve from fluid contact.
- Bi-directional stem seal is suitable for pressure and is self- adjusting.
- The disc hub edge is rounded and polished to provide full concentric seating without seat obstruction to flow, as well as to ensure maximum seat life.
- Replaceable elastomer seat isolates the shaft and body parts from the stream and also serves as the flange gasket.
- Moulded-in O-ring provides positive flange sealing and eliminates the need for additional gaskets.
- Heavy duty top bushing absorbs side thrust and torque loads.
- Heavy duty one piece shaft design provides high strength and positive disc control.
- Stainless steel disc screws allow quick and easy disassembly.
- Disc screw connection is positive shake proof and stronger than shaft.
