Parker DC-1500-5 Hydraulic Check Valve 240 Gpm 3000 Psi

Product Description

The PARKER DC-1500-5 is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic circuits. Built with a steel body and metal seals, this valve handles demanding fluid power applications where leakage past the seat is not acceptable. It accepts a 1-1/2-11-1/2 Female NPTF threaded inlet and is rated for a maximum working pressure of 3,000 psi with a maximum flow rate of 240 GPM. Compact at 6.37 inches in overall length, 2.38 inches in width, and 2.38 inches in height, it fits into tight hydraulic manifold and plumbing configurations. Fluid power technicians and hydraulic system mechanics are the primary installers of this component.

This check valve is suited for industrial and mobile hydraulic systems where positive shutoff in the reverse direction is required. Typical applications include hydraulic power units, press circuits, cylinder holding circuits, and directional control plumbing in both stationary and mobile equipment. The Female NPTF thread connection provides a pressure-tight, dryseal fit without relying on sealant, making it appropriate for high-pressure hydraulic lines where thread integrity is critical. Its all-steel and metal-seal construction makes it a fit for systems running petroleum-based hydraulic fluids in environments with elevated operating pressures.

Key Features

• Maximum working pressure of 3,000 psi for high-pressure hydraulic circuits
• Maximum flow rate of 240 GPM supports high-volume system demands
• 1-1/2-11-1/2 Female NPTF thread provides dryseal pressure-tight connection
• Steel body construction for durability in industrial and mobile hydraulic environments
• Metal seal material for positive shutoff and minimal internal leakage
• Compact envelope: 6.37 x 2.38 x 2.38 inches for installation in space-constrained plumbing runs

Compatibility

Designed as an OEM-style replacement or new-installation check valve for industrial and mobile hydraulic systems using 1-1/2-11-1/2 Female NPTF threaded connections and operating within 3,000 psi maximum working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and lock out the hydraulic system completely before removing any fittings or installing this valve. Verify thread compatibility and confirm the system fluid is compatible with steel body and metal seal construction before installation. Use of thread sealant is generally not required with NPTF dryseal threads, but follow the equipment manufacturer guidelines for your specific circuit.
