Descripción completa del producto

DT Series, In Line, Hydraulic Check Valves (up to 5,000 psi) have a metal to metal hard seat design with a one piece body and all steel construction. The body is a compact size with a variety of male port end configurations. These are in-line one way valves with standard spring crack pressures of 1, 5, and 65 psi. The DT Series hydraulic check valves are available in a wide range of sizes for flow capacities up to 100 gpm.


Hydraulic Check valves are important components that are often overlooked when building a fluid system. A check valve can optimize system performance in the following ways:

• Ensure hydraulic fluid flows in only one direction

• Eliminate potential damage from back pressure

• Isolate sections of a system or system components


Basic hydraulic check valve construction consists of a valve body with an inlet and an outlet port. Inside, a moveable poppet valve is controlled by spring pressure. In most cases the valve is normally closed, opening when the fluid pressure is greater than the spring force (crack pressure), thus allowing the fluid to flow in only one direction. When reverse flow attempts to enter though the outlet the poppet closes and flow through the valve is stopped.


Hard seat check valves utilize a durable metal to metal seal to withstand high flow surges and provide longer service life.


Technical Characteristics:

• Sizes: 1/4” to 1-1/4”

• Material: Steel

• Inlet Port Ends: Male ORB, Male JIC, Male ORFS

• Outlet Port Ends: Male ORB, Male JIC, Male ORFS

• Optional crack pressures available from 1 to 200 psi in 5 psi increments

• Orificed valve option

• Custom shapes and configurations


Note: Some options may not be standard configurations. Please contact the Quick Coupling Division for availability and delivery.


Markets:

• Industrial

• Construction

• Agriculture

• Transportation

• MRO


Features/Benefits:

• Allows the fluid to flow in only one direction (one way valve), protecting the system from fluid back pressure

• Metal to metal hard seat provides longer life and is durable for high flow surges

• Custom shapes and configurations can integrate special features to reduce the number of components and potential leak points in a system

• Optional crack pressures are available on request

• Optional orificed valve allows metered flow when the valve is closed. Orifice bore size is determined by application requirements.


Applications: 

• Industrial, mobile, and construction equipment

• Restrictor Check Circuit

• High/Low Pump Circuit

• Slow Advance/Rapid Return Circuit

• Oil Cooler By-Pass Circuit

• Sequence Circuit

• Pilot Pressure Circuit

• Accumulator Circuit
