P16/M is a pilot controller commonly used on pilot‑operated safety relief valves (e.g., PVS 803). It provides cut‑out in the 1.5–40 barg range with G¼ or EO tube connections and integrated filter. Kits replace diaphragm, seat and seals to maintain trip repeatability and leak‑tightness. For sizing and settings, refer to the safety valve or regulator manual it controls. Ensure tubing, filters and sense lines are clean; replace vent screens and check that the pilot exhaust path is unobstructed after maintenance. Safety pilot assembly for gas station service on Class 150 piping within an ambient range −20 to +60 °C (as specified). Typical selections are P16/M or similar over‑pressure pilots used with pilot‑operated safety relief valves; ensure body rating, temperature class and set range match site conditions. Include pilot diaphragm/seat and seal kits for maintenance.
