A screw-in, cartridge-style, load sense, flow-on-demand pressure-compensator with built-in damping and load-holding features for use in gravity-lowering circuits.
The EC12-34 is designed to be used in combination with a flow control valve for
lowering and holding a load. With inlet flow at port ➁, port ➂ will deliver required flow regardless of load pressure at ➁. Port ➀ of the compensator must be connected to the outlet of a flow control valve that is connnected to the tank.
• Hardened parts for long life.
• Hardened seat for low-leakage load-holding capability.
• Quiet, modulated response.
• Industry common cavity.
Operating Pressure: Inlet: 241 bar (3500 psi)
Maximum Regulated Flow: 83 lpm (22 gpm) with 200 psi compensating spring
Flow Maintenance: See performance chart
Leakage: ➁ to ➀ at 241 bar (3500 psi): 5 drops per minute when external metering orifice is closed; 160 ml (10 cu. in.) per minute when external metering orifice is open.
