Features
- Operator flange conforms to ISO 5211. Designed to work with manual, pneumatic or electric actuators.
- The rubber seat is non-collapsible, stretch-resistant, and blowout-proof.
- The precision machined disc ensures low operating torque and effective sealing up to 200 psi. The hydro-dynamically designed disc allows for high-capacity flow.
- A one-piece shaft design ensures dependability and positive disc positioning.
- The valves are epoxy coated and incorporate “zerk”-style grease fittings for easy lubrication of the neck and gearbox (if applicable).
