4" Normally Open Flanged Valve

• A diaphragm valve that utilizes a double chamber isolating the control chamber above the actuating diaphragm allowing the use of water or air to operate the valve. The slow moving diaphragm minimizes the possibility of water hammering.

• Made from glass fiber reinforced plastic.

• A special molding process to give the reinforced rubber diaphragm extra strength, abrasion resistance and long working life.
