DESCRIPTION
A screw-in, cartridge-style, load sense, pressure-compensator hydraulic valve with
built-in damping and load-holding features for use in gravity-lowering circuits.
OPERATION
The EC16-34 is designed to be used in combination with a fl ow control valve for
lowering and holding a load. With inlet fl ow at port
➁, port ➂ will deliver requred fl ow
regardless of load pressure at
➁. Port ➀ of the compensator must be connected to
the outlet of a fl ow control valve that is connnected to the tank.
FEATURES
• Hardened spool and cage for long life.
• Hardened seat for low-leakage load-holding capability.
• Quiet, modulated response.
• Industry common cavity.
RATINGS
Operating Pressure: Inlet: 241 bar (3500 psi) with standard Buna N seals.
Maximum Regulated Flow: 170 lpm (45 gpm) See performance chart.
Compensation Value: 13.8 bar (200 psi).
Maximum Leakage at port
➀: 5 drops/minute with 207 bar (3000 psi) at ➁.
Temperature: -40 to 120°C with Buna N seals.
Filtration: See page 9.010.1
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of
7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
Installation: No restrictions; See page 9.020.1
Cavity: VC16-3; See page 9.116.1
Cavity Tool: CT16-3XX; See page 8.600.1
Seal Kit: SK16-3X-MM; See page 8.650.1
