Features
Single trip valve construction reduces costs and spare part requirements of those systems using three separate switching valves to perform the failure functions. A single trip valve greatly simplifies piping requirements.
Conversion to any of the fail modes requires only minor hook-up changes.
The trip point is adjustable for specific supply pressure requirements.
The trip valve design includes large diaphragm areas and few moving parts for efficient performance, minimum maintenance, and long service life.
