The VS series of piston-spool solenoid and pneumatic valves and valve manifolds have a high flow rate and are suitable for simple clamping and locking operations. The valves can be applied in explosive environments and can be modified to meet the IP67 standard for dust and immersion resistance. The series comprises VUVS solenoid valves, VUWS pneumatic valves and the VTUS valve manifolds. The flow rate ranges from 700 l/min to 2,000 l/min. Pressure ranges from 0 to 10 bar and from 2.5 to 10 bar for internally piloted valves.
