DESCRIPTION
The ECV10-44 is a standard model EC10-40 in a convenient in-line plumbed body with an integral control cartridge cavity VC10-2 for the addition of needle valves, rotary valves, electro-proportional valves, etc., allowing for infinitely variable pressure-compensated priority flow output.
OPERATION
The ECV10-44 maintains a constant flow rate from port R regardless of load pressure changes in the circuit downstream of port R.
The cartridge maintains a constant differential pressure from port P to port R (see valve symbol), thereby regulating the hydraulic flow rate between the two ports. The ECV10-44 is a priority type regulator, delivering pump flow first to R, then bypassing excess to B. All ports may be fully pressurized. Flow output is a function of the flow required to maintain a pressure drop as determined by the compensating spring value. The control cavity is cartridge port 2 in, cartridge port 1 out, so all cartridge restrictions on 1 to 2 use apply.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Panel-mount capability.
• Lock-down bracket holes.
