Detailed Product Description:
The PV-12 Pneumatic 2-Way Diaphragm Valve is designed for use in high purity
semiconductor applications. It 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.
Precision-machined diaphragm manufactured from the latest technology modified
PTFE. Provides over five times the flexural life of conventional PTFE.
Tongue and groove seal for positive diaphragm to body seal. Provides high
cycle life, lower replacement costs and less downtime.
PVDF-coated stainless steel spring reduces effects of corrosive environments.
