structural characteristics

Wedge gate structure, with a metal hard seal between the gate and valve seat, suitable for high temperature, high pressure, and medium conditions containing particles.

Pneumatic actuator drive, strong output torque, fast response speed, can be matched with accessories such as solenoid valves and limit switches to achieve automation control.

Carbon steel cast valve body, high strength, strong impact resistance, suitable for medium and low pressure, high temperature working conditions.

The valve stem adopts an anti blowout structure, combined with a dual sealing design, effectively preventing medium leakage and improving operational safety.

Clear stem design allows for intuitive judgment of valve opening and closing status through the valve stem, facilitating maintenance.

Design specifications: comply with GB/T 12232 and API 600 standards.

Drive mode: Pneumatic (expandable to manual, electric, hydraulic).

a. Z641H-16C hard seal type: metal valve seat, suitable for high temperature, high pressure, and granular media

b. Z641Y-16C wear-resistant type: hard alloy overlay valve seat, suitable for high wear media

c. Z641F-16C soft seal type: PTFE valve seat, suitable for room temperature, medium and low pressure media
