4 Inch TI Diaphragm

Manual Plastic Diaphragm Valves

TI Diaphragm Valve (1/2" – 6")

Specifically designed for processing chlorines and chlorates in chlor-alkali and caustic soda production plants. The new valve features an injection-molded, solid PVDF flanged body with a strong and durable PPG bonnet. This field proven and industry preferred valve also boasts features that help eliminate the corrosion of stainless steel fasteners common in such applications. The Ti Type-14/15 Diaphragm Valve is designed with a unique three-layer construction: an EPDM backing cushion; a PVDF gas barrier; and a layer of PTFE – the only wetted part. Superior corrosion protection is achieved by offering a palladium-titanium diaphragm insert that connects the diaphragm to the valve compressor via a palladium-titanium stem connection joint. Light weight and corrosion resistant titanium bolts, nuts, washers, studs and body inserts sandwich the diaphragm between the body and bonnet creating a reliable seal.

Available in sizes of ½" through 4", the Ti Type-14/15 is suitable for temperatures of up to 250oF, and working pressures of up to 150 psi. Can be pneumatically or electrically actuated.

Ideal Applications Include:

Corrosive environments, mining, throttling, slurry lines, chemical processing, bleach plants, aquariums, water treatment, landfills, swimming pools, semiconductor manufacturing
