COVNA HK59-D-P Pneumatic Actuator PVC Butterfly Valve
COVNA HK59-D-P Pneumatic Actuator Plastic PVC Butterfly Valve With Fluorine Lined is widely used in the sealing surface material of sanitary valve. With good sealing performance, it is also widely used in vacuum system etc. Pneumatic Actuated PVC Butterfly Valve make ideal for water and light industrial applications. The special trapezoidal shape of the bushing and the jagged cavity ensures an air-tight seal while keeping the separation torque to an absolute minimum. This multi-function valve has a double self-lubricating seal, the function of directly mounting the actuator, or the option of a handle or a gear box or Actuator.
- Model: HK59-D-P
- Size Range: 2"-24"
- Pressure Range: 1.0MPa
- Material: PVC, CPVC, UPVC, PVDF
