3/4" - 1", 100 psig | MV-12 series Partek Division

The MV-12 Series is designed for semiconductor, ultra-pure water and aggressive chemical or gas applications. The design utilizes a molded high purity PFA body with precision machined seat and diaphragm sealing areas. A one piece machined modified PTFE diaphragm is also utilized for excellent flexibility and life. The valve requires three full turns from the fully closed to fully open position. A full 1” orifice provides maximum flow capability in a compact package.

Product Features & Benefits:

· One piece precision machined diaphragm manufactured from latest technology modified PTFE. Provides over five times the flexural life as compared to conventional PTFE. Tongue and groove seat and diaphragm for positive through flow shut off and diaphragm to body seal which can create higher cycle life resulting in less downtime and lower replacement costs.

· PVDF coated stainless steel spring reduces effects of corrosive environments.

· Submergible option isolates all valve components from the external environment therefore valve remains functional while operating in wet of gaseous corrosive environments.
