Pressure Relief Valves SPV/SPVF direct operated Pressure Relief Valves SPV, SPVF direct operated Housing Sliding piston Compression spring Set screw Bleeding screw Protective cap Valve Construction The pressure relief valve SPV/SPVF is a direct spring sliding piston valve. It is intended for mounting in pipelines and is suitable to safeguard low pressure hydraulic circuits. The pipe connection is to be effected either by SAE-mounting surfaces (3000 psi) or by Whitworth pipe threads ”G“. The sIiding piston 2 is pressed against the annuIated area a by the compression spring 3. Thus the pressure...

Pressure Relief Valves SPV/SPVF direct operated Pressure Relief Valves SPV, SPVF direct operated ATEX Explosion protection – Field of application for the pressure relief valves. The valve is used to secure low pressure hydraulic circuits with various flammable and non-flammable fluids. They can be used: a In Zone 2 (Gas-Ex, Category 3 G) in the explosion groups IIA, IIB and IIC b In Zone 22 (Dust-Ex, Category 3D), in the explosion groups III A and III B at non-conductive dusts with a minimum ignition energy >1mJ c In Zone 1 (Gas-Ex, Category 2 G) in explosion groups IIA, IIB and IIC d In Zone...
