SV AND SVX-50 DIRECTIONAL CONTROL VALVES

The ShearFlo® SV-50 directional control valve ensures negligible internal leakage and contaminant resistant operation for 1/2” or 3/8” piping. Its modular design allows for various operator and porting options to suit numerous high-pressure, critical service applications.

The SVX valve with integral actuator* is recommended for reliable remote and long-term cost saving applications in need of a compact footprint. The SVX shares all the benefits and replaceable ShearFlo® sealing components as the SV valve but is integrated with a rack and pinion style actuator with double-acting pistons. Actuation type may be configured for air or hydraulic that is direct or solenoid piloted in 2 or 3 positions or spring centered. For remotely operated hydraulic control systems demanding a small footprint with minimal labor, the patented PacSeal integral control valve manifold can easily be fitted with the SVX.
