Valcor Engineering Corporation

Scientific & Industrial Miniature Isolation Valves

Description

Ranging in size from 3/4” to 1.5” in diameter, the Valcor Scientific family of Miniature Isolation Valves are available in direct acting two-way normally closed / normally open, and universal three-way operating modes. Made with all PTFE, PEEK, PPS, or PCTFE wetted parts, body configurations include threaded ports, surface mount, and inline and gradient manifolds. Compact size, low internal volumes, and low power consumption set our offering apart from the rest of the industry.

Application

Utilizing a PTFE isolating diaphragm to seal on the PTFE body seat, these highly inert valves are capable of handling a wide range of corrosive or high purity fluids and gases. Fully bi-directional, they are rated at vacuum to 30 psi as standard, with 100 psi as a high pressure option. Typical applications include medical and analytical instrumentation, chemical and process analyzers, liquid and gas chromatographs, and mass spectrometers.
