Diaphragm valve for high purity applications Partek Division
PTFE

The PV-12 Pneumatic Diaphragm Valve is designed for use in high purity semiconductor applications, and is also ideally suited for 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. A full 1" orifice provides maximum flow capability in a compact package.

FEATURES:

* Precision machined diaphragm manufactured from the latest technology modified PTFE. Provides over five times the flexural life as compared to conventional PTFE. Tongue and groove seal for positive diaphragm to body seal. Benefits are high cycle life, lower replacement costs and less downtime.
* PVDF coated stainless steel spring reduces effects of corrosive environments.
* Submergible option isolates all valve components from the external environment, which allows valve to remain functional while operating in wet or gaseous corrosive environments.
