Speed Valves

The Speed-Valve series is a range of regenerative valves increasing the speed of the forward movement of a double acting cylinder. This is achieved by diverting the oil from the B-side of the cylinder to the A-side. The total flow used to move the cylinder forward is then QA = Qpump + QB. The Speed-Valves will not affect the return speed of the cylinder. The Speed-Valve Type VA has a unique built-in control valve, which automatically changes from speed to force when the cylinder meets resistance in the forward direction. The Speed-Valves are designed as in-line valves, and easily installed into any hydraulic circuit. No additional controls are needed, as the  Speed-Valves are controlled by the control valve in the system.

Scanwill SVA series speed valves make it simple to produce regenerative, double-acting hydraulic cylinder performance by adding a standard component to a conventional circuit. Rated for pressures up to 5,000 psi (350 Bar), two SVA series models handle flows of up to 31.7 and 52.83 GPM (50 and 200 LPM). They suit new installations or retrofits and are compact in size. All fluid connections have 3/8” BSP threads. Speed valves do not affect cylinder retraction.

Speed Valve SVA-050

The Speed-Valve SVA-050 has a unique built in control valve, which automatically connects the rod side of the cylinder to tank when the cylinder meets resistance in the forward direction. This means the SVA-050 combines high flow and full force.

Materials: The SV-050 is made from cast iron and steel, and the valve has a zinc-chromate surface coating. The SV-050 can be made in stainless steel on request.

Fluids: Suitable for most recognized hydraulic oils and water glycol.

Pressure Rating: 5,000 psi (350 Bar)

Flow Rating: 13.21 GPM (50 LPM) (pump setting)

Filtration: 20 micron nominal

Connections: 3/8” BSP

Cylinder Force: Due to the integrated control valve the SVA-050 automatically connects the rod side of the cylinder to tank when there is a resistance or the cylinder is fully extracted. That means the full force is always available when needed. The SVA-050 has no influence on the performance of the cylinder when retracting.

Speed Valve SVA-200

Materials: The Speed-Valve is made from cast iron and steel, and the valve has a zinc-chromate surface coating. The SVA-200 can be made in stainless steel on request.

Fluids: Suitable for most recognized hydraulic oils and water glycol.

Pressure Rating: 5,000 psi (350 Bar)

Flow Rating: 31.7 GPM (120 LPM) with 3/4″ BSP ports (pump setting) or 52.83 GPM (200 LPM) with 1” BSP ports (pump setting)

Filtration: 20 micron nominal

Connections: 3/4″ BSP max. flow 31.7 GPM (120 LPM) (pump setting) or 1” BSP max. flow 52.83 GPM (200 LPM) (pump setting)

Cylinder Force: Due to the integrated control valve the Speed-Valve type SVA automatically connects the rod side of the cylinder to tank when there is a resistance or the cylinder is fully extracted. That means the full force is always available when needed. The Speed-Valve Type SVA has no influence on the performance of the cylinder when retracting.
