2 Position, 2 Way Normally Open Poppet Type Manual Valve

Parker’s selection of 2-position, 2-way normally-open manual poppet valves provide a low leak solution to simple 2-way manually operated circuits. These valves are capable of flows up to 45 lpm (12 gpm) and pressures as high as 350 bar (5000 psi). Parker’s 2-position, 2-way normally-open manual poppet valves have push button style manual controls with an optional screw-in detent or 60-micron mesh pilot screen. These valves are ideal for on/off style applications, such as emergency lift/lower circuits or simple actuators on a variety of machinery within the construction, material handling, or industrial markets.

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

Features/Benefits:
• Hardened poppet for minimal wear and greater durability
• Internal pilot provides power leverage
• Low leak poppet design
• Screw-in detent optional
• External parts zinc plated

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

Additional Technical Insight:
When the valve is not being actuated by an operator, pilot flow is allowed to pass from port 2 to 1 which causes the main poppet to lift allowing full flow from port 2 to port 1.  Once an operator presses the actuator the pilot is forced into its seat which blocks pilot flow and causes the main poppet to firmly close preventing flow from port 2 to port 1 with less than 5 drops per minute leakage.

In the unactuated condition flow is restricted from port 1 to port 2 through the pilot section, but the main poppet will remain closed.  Push button and detented knob actuators are standard and a 60 mesh pilot screen is optional.
