The Valv-Trol Two-Pressure Operating “Valve” is actually anassembly of three of our standard valves. This “valve” has proven to be an efficient and economical way to actuate a single acting hydraulic press or cylinder. The use of a low pressure fluid for most of the stroke conserves high pressure fluid which is more costly to generate. When the ram meets resistance near the end of its stroke,the higher pressure fluid can be applied automatically for final squeezing or clamping.
Each assembly is made up of a Balanced 3-Way Valve, an Angle Check Valve, and a High Pressure Inlet Valve. Our popular model B-0511 automatic inlet valve is standard with all sizes. It can be adjusted to open when ram pressure builds up to any point between 150 and 400 PSI (10 and 28 Bar). Optional to automatic valves are shown on Bulletin A-7. Our model C-0008, 2-way Normally Closed Diaphragm Valve is often used if separate control is more desirable than automatic operation
Each valve is an independent unit Can be mounted in the most convenient position for simplified piping.
