Check valve, also known as check valve or check valve. Used in hydraulic system to prevent reverse flow of oil. Check valves are straight-through and right-angle two. Straight through check valve with threaded connection installed in the pipeline. Right angle check valve threaded connections, plate connections and flange connections in three forms. Hydraulic check valve, also known as the lock valve or pressure control valve, which is the same with the one-way valve to prevent reverse flow of oil. However, in the hydraulic circuit, when the reverse flow of the oil flow is needed, the oil pressure can be controlled and the check valve can be opened so that the oil flow can flow in both directions. Hydraulic check valve with tapered spool, so good sealing performance. When required to close the oil circuit, this valve can be used as a one-way locking oil pressure from the packing effect. Leakage check valve control oil leak-type and leakage of two types. In the reverse flow of oil flow without back pressure in the internal discharge available; otherwise need to leak, in order to reduce the control of oil pressure.
Three Screw Pump be used transfer many kind of oil, like: diesel fuel oil, lube oil, engine oil etc, temperature can not over 150 degree. three screw oil pump's flow rate and pressure all higher than Gear Pump's, so when gear pump can not meet customer's requirment we will choose three screw oil pump for customer. this kind of pump smooth operation, low noise, widely used in various industries. heat insulation jacket three screw pump can be used to transfer high temperature high viscosity oil and bitimen. pump max can bear 300 degree.
