Key Features & Benefits
Requires less space compared to gate valves and weighs significantly less, reducing structural support needs.
90-degree rotation provides fast opening/closing with minimal torque requirements.
Precision-machined disc and resilient seat ensure zero leakage when closed.
Streamlined disc design minimizes turbulence and pressure loss when fully open.
Available with spring-return actuators for fail-open or fail-close operation.
Visual position indicator shows valve status at a glance.
