Natural Gas Manifold Valves

Designed for use with differential pressure transmitters incorporating two isolation valves, two equalizing valves and a vent valve required in natural gas applications
Flare Pattern? valve configuration provides maximum clearance for fingers during operation
Soft tip valves feature a patented Delrin? non-rotating soft tip stem, and a back-up metal-to-metal seal (U.S. Patent 6,820,857)
