structural characteristics

Y-shaped angular flow channel design ensures smooth medium flow, reduces particle retention and pipeline blockage, and is suitable for media containing particles and high viscosity.

Pneumatic thin film actuator drive, stable output force, coupled with valve positioner, can achieve high-precision flow regulation.

The valve core is made of hard alloy overlay, which is wear-resistant, erosion resistant, and suitable for high wear medium working conditions.

Carbon steel cast valve body, with high strength and strong impact resistance, suitable for harsh working conditions such as medium and low pressure and particle content.

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

Design specifications: comply with GB/T 4213 and API 600 standards.

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

a. ZJHY soft seal type: PTFE valve seat, suitable for room temperature, medium and low pressure media

b. ZJHY hard seal type: metal valve seat, suitable for high temperature, high pressure, and granular media

c. ZJHY wear-resistant type: hard alloy overlay valve core, suitable for high wear media
