Hydraulic Control Valve is the most efficient valve for automatic operation of industrial and municipal distribution systems or any other system that requires adjustable working conditions.
The valve operates by pipeline water pressure and does not require any other external energy source. The valve is a completely independent device and can be installed at any location in the pipeline, provided there is just a minimum water pressure allowing its operation. An operating piston surface double the size of the sealing surface enables the control chamber movement towards opening or closing with no external force or energy required.
The G type is a piston actuated valve, which varies from 2” to 32” in a pressure ranging from PN-16 to PN-64.
Raphael G type, globe pattern, piston actuated control valves are a heavy duty, high pressure and large diameters throttling valves.
As a piston actuated valve it is specially designed to withstand high restriction levels at a wide range of flow and diameters.
The metal construction of the piston enables a smooth operation, with no vibrations. Bronze and Stainless steel internal parts provide a cavitation resistance at very low flows keeping metal and iron parts of valves from being damaged. Low corrosion rates are obtainable due to high quality bronze and stainless steel internal parts and high quality epoxy or enamel coating (Potable water approved).
Regulation in high restriction rates is obtainable by a half restricted plug that combine a cost effective protection to seat and seal, keeping sensitive parts in the valve from high velocity water passage.
Globe pattern body construction gives equal wear for the control unit, thus prolonging its lifespan.
