Features- Dual Pattern ISO 5211 Direct Mount Pad:
- No mounting kit needed for automation.
- Eliminates exposed moving parts for safer work environment.
- Direct drive eliminates play and improves actuator positioning.
- Dual pattern pad fits a wide range of actuator sizes.
- High-Cycle, Live Loaded Stem Packing:
- Spring energized stem seals self-adjust to compensate for wear, pressure and temperature changes ensuring a leak-tight seal and extending service life.
- O-Ring Stem Bearing:
- Maintains stem alignment.
- Reduces packing side-loading and wear.
- Enhances stem seal.
- Blow-Out-Proof Stem:
- Stem is bottom loaded to prevent removal when valve is in service.
- 3-Piece Design:
- Swing-out construction makes the valve easy to repair in line. Universal Valve Body:
- Same center section can be used for both manual and automated service.
- Locking Device:
- Enables plant personnel to secure valve in open or closed position when manually operated.
- Heavy Duty Construction:
- Investment Cast:
- High quality investment castings improve dimensional control and reduce porosity; certified material test reports are available upon request.
- Heavy Duty 410 SS Bolts (336 only)
