Miniature pneumatic valve for high purity applications Partek Division
PTFE

The PV-1 Miniature Pneumatic Diaphragm Valve is designed for use in high purity semiconductor applications, and is also ideally suited for ultra-pure water and aggressive chemical systems. The design utilizes a machined modified PTFE body, seat and diaphragm ensuring excellent flexibility and long life. The valve is available in 2 and 3 way configurations. It is ideal for low flow and small dose injection applications.

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, less downtime and isolates media from actuator.
* Compact design allows for ease of installation and maintenance.
