High Temperature Alloy Spring
Features and Benefits
- Heavy duty construction of high quality cast steel with Stainless Steel full-nozzle trim for optimum performance.
- Bolted yoke design for easy maintenance.
- Steel yoke incorporates a cover-shield for guiding surfaces and provides for fully exposed spring.
- Seats lapped to optical flatness for tight shut-off
- Dual control rings offer easy adjustability for precision opening with minimum pre-open or simmer and exact blowdown control.
- Every valve 100% tested/inspected for pressure setting, blowdown and leakage.
- All adjustments are factory sealed to prevent tampering or disassembly.
