Pressure Reducing Valves By Hvc Engineering & Technoologies

We are engaged in manufacturing and supplying of Pressure Reducing Valves in Mumbai, Maharashtra, India. Operation is such that reduced outlet pressure is maintained constant regardless of variation of inlet pressure above selected pressure setting.
Oil Viscosity ranging between 150 and 225 S S U at 40 C for ambient temperatures above 20 C is recommended.
Adjustment of reduced outlet pressure is accomplished by loosening Lock nut and turning pressure adjustment control. Clockwise rotation increases pressure and anti clockwise rotation decreases pressure control adjustment has stops for minimum and maximum pressure.
Drain Connection must be piped directly to tank. Maximum Inlet Pressure recommended 3000 psi, Outlet Pressure range 100 psi. A differential of at least 150 psi between inlet and outlet pressures must be maintained for proper functioning.
Hydraulic Fluids For Oil Hydraulic System using high quality lubricating oil as per standard Hydraulic oil specifications is recommended. These valves can be used for water-glycol and water-in-emulsion fluids when fitted with standard seals.
