Detailed Product Description:

The Partek PV-10 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 1/4” 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.
