EATON Gromelle 格羅梅爾 R4000系列單向閥
Gromelle 格羅梅爾 R4000系列止回閥用于液壓線路。該系列產品堅固可靠，壓降小且配有彈性體單向閥密封件，可實現無泄露操作。可選尺寸為1/4”至1/2”。Eaton R4000 Series steel check valves are designed for multipurpose hydraulic applications to either allow flow of fluid
in one direction only or limit the line’s internal pressure to the cracking pressure. Standard cracking pressures are 0.5 and 1 bar (7.25 and 14.5 psi). Alternatives can be offered upon request.
