Parker Ermeto DIN check valve EO kontra ventil chromated steel 18 deg 1/2 A

EO-PSR fittings produce high pressure, leak free connection of tubes and components in hydraulic systems. The basic function of EO-PSR is the controlled progressive bite of the EO-PSR into the tube due to a unique internal geometry. Assembly process is according to the EO-Progressiv ring instruction. The design allows a 100 %-preassembly for an easier final assembly. Features, advantages, benefits of the EO-PSR fitting range: High corrosion resistance: The Cr(VI)-free surface treatment causes an average corrosion resistance of more than 500 hours to white rust. High pressure: EO-PSR can be used in applications of up to 800 bar (S series) and 500 bar (L series). EO-LUB: Due to the special treatment of larger sized nuts (25S/28L and larger), the tightening torques of EO-PSR fittings have been reduced by 25%. This makes assembly easier and prevents underassembly. Safe assembly: Two distinctive cutting edges provide a progressive increase of the tightening torque of the EO-PSR. The noticeable end point of assembly contributes to maximum safety of assembly. Multifunctional ring geometry prevents over-tightening. EO-PSR is available worldwide and meets the requirements of the applicable standards for 24° cutting ring fittings. Applications: Machine tools, mobile hydraulics, shipbuilding/offshore, transportation • Automotive • Defence • Energy • Environment • Industrial • Infrastructure • Machine Tools • Materials Handling • Mobile • Oil and Gas • Power Generation • Process • Transportation • Water • The precise functioning of Parker non-return valves has been proven a million times over and stands for the reliability of this product range. • Combined soft and metal sealing – leak-free due to soft sealing at cone and metal-supported sealing at cone – extends the safety of the product and the entire hydraulic application. • The usage of Parker non-return valves is flexible due to the wide range of items. • For yet more applications, internal parts in stainless steel with FPM are also available. • Parker non-return valves are all packed against contamination, which improves the quality and reliability of these products. • Suitable for general hydraulic applications.
