Ningbo Zhenhai Finotek Machinery Co.,Ltd is one of the leading China direct acting relief valve manufacturers and suppliers in China,Website:http://www.finotekpower.com, welcome to buy or wholesale customized bulk direct acting relief valve from our factory.DBD Direct acting relief valve consists of a poppet or ball, hold exposed to hydraulic system pressure on a side and opposed side by a spring of pre-setting pressure on the other. Finotek direct acting relief valve is easily adjustable in normal or high pressure, it is setting with normally closed pressure relief valve. While the pressure in the inlet port utilized by the compress spring exceeding the pressure exerted by the pressure in hydraulic system acting the side of hardened ball or poppet. The spring holds the steel ball or valve poppet tightly seated, the port of reservoir on the spring side of the valve, called T port, returns the fluid leakage to tank directly. Finotek directing acting relief valve is usually used as safety valve to protect the normal pressure in hydraulic systems. Specifications of direct acting relief valve:Order code: DBD6, DBD8, DBD10, DBD15, DBD20, DBD25, DBD30  Max. operation pressure: 40Mpa, 400barMax. flow rate: 50L ~ 350LValve Inner leakage: 5drops /min. max. at 70MpaAdjustment pressure range of direct acting relief valve :Max. pressure stage: 25bar;Max. pressure stage: 50bar; Max. pressure stage: 100bar;Max. pressure stage: 200bar; Max. pressure stage: 315bar;Max. pressure stage: 400bar; Valve 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
