Dual Pneumatic Diaphragm Valve (DPDV)
Dual Pneumatic Diaphragm Valve (DPDV)
Dual’s Pneumatic Diaphragm Valve consists of a tough but flexible Diaphragm in an enclosed body. Actuated by means of air or hydraulic fluid, the valve acts as an actuator. When the media is introduced, the sleeve is compressed and forming a complete and effective seal. All bodies and bonnets are made from a high grade SG 42 Cast Iron or Cast Aluminium and is suitable for lining with various Rubber, Urethane, Ceramic, Halar and Butyl.
