Pressure Reducing Pilot Valve Model PC-20-P This pilot integrates all principal functions of a 2-way control circuit in a single assembly. It is a direct acting pilot valve, actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring forces. When used in a pressure reducing circuit, the pilot modulates closed as downstream pressure rises above set point. An internal restriction acts as an upstream flow restrictor. Features ■ Internal or external upstream flow restrictor ■ Internal or external pressure sensing ■ Differential pressure sensing Typical Applications ■ Pressure Reducing Valves sizes IV2-4” (Standard model #PC-20-P) ■ Closing Surge Control (additional feature 49) for sizes 1V2-4” (Modified to external pressure sensing PC-20-P-R) Technical Data Pressure Rating: 10 bar; 145 psi Working Temperature: Water up to 50°C; 122°F Flow Factor: Kv 0.22 rrP/h @ 1 bar AP; Cv 0.25 GPM @ 1 psi AP Standard Materials: Body & Cover: Polyamide 6+30% F.G Elastomers: NBR Internals: Stainless Steel & Brass Spring: Galvanized Steel Ports: i/s" NPT Adjustment Range Standard Optional Connections 0 - Upstream 3 - Valve control chamber 2 - Downstream 1 - Plugged/ External Sensing The information herein is subject to change without notice.
