PC Series Inline Pressure Compensated Flow Control Valves, Up To 3000 PSI & 30 GPM

Description & Features

Application	Flows are controlled within ±15% up to 1.5 GPM and at ±10% at higher flows up to 30 GPM. Regulation is virtually unaffected by temperature changes from 60°F to 180°F (±2% at 70°F DT, ±4% at 120°F DT). Series 3 and Series 4 models have a restricted reverse flow as limited by the internal orifice. Series 5 models have a free reverse flow.
Features	Maintains accurate constant flow at pressures up to 3,000 PSI (Non-shock service). Fixed (Factory set PC3 and PC4 models) and Adjustable (PC5 models). Free reverse flow (PC5 models).
Materials	Steel body (PC3 and PC5 models), Aluminum body (1/4 and 3/8 PC4 models), Steel body (1/2 and 3/4 PC4 models. Viton® O-Rings. Aluminum knob (PC5 models).
Temperature Range	-15°F to 400°F.

Question by: Dean O on Aug 21, 2025, 12:43 PM

How precise is the flow control on these things? I need something that's pretty consistent.

Regulation is quite accurate. Within plus or minus 15% up to 1.5 GPM, and within 10% at higher flow rates up to 30 GPM.
