Designed for directional control and load-holding applications, SVCL and SPCL series valves offer operating pressure of 3,625 psi and holding pressure of 5,000 psi at port 1. They feature VC10-3 cavity with modified pre-drill and 5 drops per minute leakage. Rated flow for SVCL and SPCL is 15 gpm at 175 and 225 psi differential, respectively. SVCL valves use HydraForce D-Series and E-series coils with various connector options.

New Patent-Pending Solenoid-Operated On/Off or Proportional Valves with Integral Piloting or Load-Signaling Capability
The new HydraForce SVCL and SPCL series valves offer the unique capability of providing integral piloting or load-signaling in a solenoid-operated on/off or proportional cartridge valve. This is an efficient, compact and cost-effective solution for directional control and load-holding applications. Patents are pending for these unique and innovative new valves, allowing us to offer the most advanced, high-performance hydraulic circuits in the industry.
The SVCL and SPCL products are initially released in the 10-size version, using the common VC10-3 cavity profile with a modified pre-drill as shown in the catalog. Other sizes are in development which will allow a flow range capability up to 40 gpm or 151 lpm. Rated operating pressure is 3625 psi / 250 bar while the load-holding port 1 is capable of 5000 psi / 350 bar maximum pressure and is qualified to 4:1 burst pressure per ANSI test specifications.
The SVCL valves use HydraForce D-Series and E-series coils with various connector options. E-series environmental coils are rated IP69K. They have been extensively tested and approved under severe mobile machinery application conditions. Coil test and option details are available at http://www.hydraforce.com/Electro/Electcon.htm
