FA49H Flanged Explosion Proof Wave Safety Valve DN50-DN200 1.0-1.6MPa Cast Steel Stainless Steel

FA49H series explosion-proof wave safety valve is a specialized water safety device that combines water hammer elimination and blocking capabilities. Featuring a multi-set safety valve configuration with buffer spring structure, this valve provides comprehensive protection that cannot be achieved by single safety valves.

During water hammer formation, the buffer spring system dissolves minor pressure waves before they cause damage. When water hammer reaches levels sufficient to damage downstream equipment, the safety valve group activates, discharging pressure from the valve chamber to protect system components from impact.

• Safe and reliable operation with no recalibration required after activation
• Extended service life with continuous operation capability
• Full-channel streamlined design for low fluid resistance and high flow rates
• Double-sealed connections using gaskets and sealing rings to prevent external leakage
• Dual guidance system for valve body, piston cylinder, and piston ensuring smooth, reliable movement
• Detachable valve seat design for convenient maintenance and replacement

Installed at the head of water supply engineering pipelines and civil defense systems, the FA49H combines wave blocking and attenuation to prevent water hammer shock waves from entering system water supply networks, protecting facility operation and safety.
