Industrial 24RV16 CP33145 Hydraulic Relief Valve

Sigma 24RV16 CP33145 hydraulic relief valve delivers precise, overpressure protection for hydraulic systems up to 10,000 psi, wired as a compact, two-position, normally closed relief device with 1/4-18 inch female NPT inlet and exhaust ports. The valve stands 6 inches tall with a 1-3/4 inch diameter body and features a.125 inch orifice with a Cv of 0.33, providing predictable relief flow at the set pressure. Wetted components are 316 stainless steel, 17-4PH stainless steel, and tungsten carbide, while Viton seals suit hydraulic-fluid service across a temperature range of -20°F to +250°F (-29°C to +121°C). Weighing about 2 pounds, the unit is designed for insert-into-relief-port installation, with guidance to use appropriate thread sealant on port connections. The CP33145 designation aligns with Sigma’s 24RV16 family, a field-ready solution for protecting hydraulic power units, presses, and other industrial machinery from overpressure conditions by venting excess fluid when the preset threshold is reached and reseating as pressure recedes. This relief valve is intended for hydraulic fluid service and supports reliable, repeatable pressure relief in demanding applications where compact size and robust materials are essential.
