***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth M-SR 20 KE30-1X/V (R900420865) is a high-quality check valve designed for hydraulic applications that require leakage-free blocking in one direction. It is a cartridge design that can be integrated into block designs, either as an angle valve or a straight-through valve. This product is part of the MSR family and features a poppet type spool for reliable operation.
With its direct acting mechanism, the M-SR 20 KE30-1X/V ensures consistent performance without the need for pressure presetting. The nominal flow and maximum flow capabilities of this check valve are aligned with its intended applications, ensuring efficient fluid control within hydraulic systems. The maximum operating pressure it can withstand highlights its robustness and suitability for demanding environments.
The sealing material used in this model is FKM, known for its high resistance to heat and chemicals, contributing to the durability and longevity of the valve. Furthermore, it supports a variety of hydraulic fluids including HL, HLP, HETG, HEES, HEPG, and HFDU, offering versatility in different hydraulic systems.
This Bosch Rexroth check valve is designed to cater to various cracking pressures which are optionally available to suit specific application requirements. Its size and component series X designation indicate its compatibility with different system configurations. The weight specification suggests ease of handling during installation or maintenance procedures.
In summary, the M-SR 20 KE30-1X/V provides reliable performance in controlling fluid direction within hydraulic systems while offering flexibility in terms of installation type and compatibility with various hydraulic fluids.
