Type 2900 Pilot-Operated Safety Relief Valve

The Type 2900 modular pilot-operated safety relief valve (MPV) combines the full nozzle construction of the Type 1900 main valve design with the extremely versatile pilot valve options from the 3900 MPV design. Typically provided with a metal-to-metal seat, this pilot-operated safety relief valve can be used over a broad temperature range.

Includes pilot line pressure snubber to minimize chatter from rapid pressure excursions and water hammer for Section 1 liquid applications.
