FireWall Valves

 

​

​

 

Two-Door Wafer Check Valve has torsion springs that force the two doors to shut before flow reversal, reducing the water hammer potential that normally occurs with single-door swing check valves.  To help reduce water hammer, the two-door Check Valve design also reduces the travel distance from open to shutoff for a quicker response.  Extremely short in lay length, the valve is both a compact and an economical solution. 

 

Advantages include:

Low Head Loss

Resilient Seat

Non-Slam Closure

Factory Mutual Approved – Various Sizes

Corrosion Resistant Material of Construction for Seawater Applications

 

Size 2" to 16"

FireWall wafer double door swing type check valve that allows water flow in one direction only. A hinged clapper remains open with water flowing in one direction and automatically closes when the flow stops preventing backflow. These valves are suitable for horizontal or vertical installation with the flow upwards.
