Half Shaft Wafer Butterfly Valve Without Pin

The Wafer Butterfly Valve with Half Shaft and Without Pin is an advanced flow control solution designed for water supply, HVAC, and general industrial applications. Unlike conventional designs, this valve features a one-piece disc-shaft connection on one side (half shaft) and eliminates the pin between the disc and shaft, reducing potential leakage points and enhancing sealing integrity.

Key Features:

Pinless Design: The disc and shaft are integrally connected without a pin, avoiding common failure points and ensuring a tighter seal.
Half Shaft Structure: Simplifies internal structure, reduces weight, and facilitates easier maintenance.
Compact Wafer Type: Easily fits between flanges, compatible with PN10, PN16, and ANSI 150 standards.
Durable Materials: Ductile iron body with SS416 shafts, PTFE bushings, and EPDM sealing components ensure long-lasting performance in water systems.
Low Torque Operation: Optimized disc-seat geometry provides smooth operation and lower actuation torque.
