| Message: | Ningbo Zhenhai Finotek Machinery Co.,Ltd is one of the leading China cartridge pressure relief valve manufacturers and suppliers in China,Website:http://www.finotekpower.com, welcome to buy or wholesale customized bulk cartridge pressure relief valve from our factory.Finotek cartridge pressure relief valve is cartridge style, screw-in mounted, pilot operation pressure relief valve, it is available to be assembled in hydraulic manifolds or valve subplate in order to control the pressure in hydraulic circuit, it keeps the hydraulic pump to work normally while the system pressure near the pre-setting pressure. There are 4 different pressure ranges for optional with high max. pressure is up to 350bar. Cartridge pressure relief valve consists of a main balance keeping spool and a pilot stage. When the main spool closed normally, the pressure will open the circuit pressure and exceeds the pre-setting pressure by the pilot stage, replacement of excess flow in T port where connects to the tank directly.Specifications of cartridge pressure relief valve:Max. operation pressure: 42Mpa, 420barMax. flow rate: 31.7Gpm/120Lpm at pressure of 420bar/6000psiValve Inner leakage: 5drops /min. max. at 70MpaPre-setting pressure:A: 0.5~55bar, pre-setting pressure: 47barB: 35~140bar, pre-setting pressure: 48barC: 70~280bar, pre-setting pressure: 88barD: 140 ~ 420bar, pre-setting pressure: 140barValve working temperature: -22° F to +250° F (-30°C to +120°C)Solenoid voltage range: voltage tolerance from 90% 110%.Medium: Mineral-based fluids better |
