Key features

High Flow Capacity: Flow capacity is 20-25% larger than single-seat valves of the same diameter.

Large Pressure Difference: Unbalanced forces offset each other, allowing operation under large pressure differences.

Multiple Material Options: Body available in Carbon Steel (WCB) and Stainless Steel (304, 316, 316L).

Versatile Actuator Models: ZHA/B multi-spring diaphragm actuators with various active areas and strokes.

High Adjustment Accuracy: Features simple connection and reliable performance for precise control.

Comprehensive Certifications: Certified with GS, CE, and ISO9001 standards.

Dual Seat Design: Double seats provide strong flow capacity but result in higher leakage.

Product Q&A

Q:What is the difference between double-seat and single-seat valves?

Double-seat valves can withstand larger pressure differences and have higher flow capacity, but they have larger leakage. Single-seat valves have smaller leakage but can only withstand small pressure differences.

Q:Is this valve suitable for high viscosity media?

No, due to the complex flow path and serious erosion/cavitation damage at high pressure differences, it is not suitable for high viscosity or fiber media.

Q:What materials are available for the valve body?

The body material options include Carbon Steel (WCB) and Stainless Steel (304, 316, 316L).

Q:What is the nominal pressure range?

The nominal pressure options are PN16, PN40, and PN64MPa.

Q:What are the available actuator models?

Available models include ZHA/B-11, ZHA/B-22, ZHA/B-23, ZHA/B-34, ZHA/B-45, and ZHA/B-56.
