Full Product Description

Parker’s selection of 2-position, 2-way normally-closed manual poppet valves provide a low leak solution to simple 2-way manually operated circuits. These valves are capable of flows up to 49 lpm (13 gpm) and pressures as high as 210 bar (3000 psi). Parker’s 2-position, 2-way normally-closed manual poppet valves are available with knob, stem, lever, or lock pin manual controls in a normally-closed configurations and are ideal for on/off style applications, such as emergency lift/lower circuits or just simple actuation or motor control on a variety of machinery within the construction, material handling, or industrial markets.

Markets:
• Construction
• Material Handling
• Miscellaneous Industrial
• Miscellaneous Mobile

Features/Benefits:
• Low leak poppet design
• External parts zinc plated

Applications:
• On/off applications
• Emergency lower/actuate applications

Additional Technical Insight:
DL081 is a manually operated 8 GPM (30 LPM) check valve that is rated for 3000 psi (210 Bar) and has leakage rates of less than 5 drops per minute. In the unactuated state oil at port 2 is prevented from exiting port 1. Once the valve is actuated, oil is allowed to pass from port 2 to port 1. Back pressures on port 1 greater than 80 psi (5.5 Bar) will prevent the internal spring from closing the poppet, so care should be taken to ensure port 1 is plumbed back to the reservoir with minimum restriction. Knob, Stem, Lever, and Lock Pin actuators are standard options.

DL101 is a manually operated 13 GPM (49 LPM) check valve that is rated for 3500 psi (240 Bar) and has leakage rates of less than 5 drops per minute.  In the unactuated state oil at port 2 is prevented from exiting port 1. Once the valve is actuated, oil is allowed to pass from port 2 to port 1. Back pressures on port 1 greater than 250 psi (17.3 Bar) will prevent the internal spring from closing the poppet, so care should be taken to ensure port 1 is plumbed back to the reservoir with minimum restriction. Knob and Stem actuators are standard options.

Parker’s DL081 and DL101 manual check valves are ideal for emergency lowering applications and for on-off applications where manual actuation is desired to allow flow to return to a reservoir with limited back pressure.
