Direct Acting Pressure Relief Cartridges (RD*A)
Applications
This patented, direct acting, differential area valve with broad operating characteristics is adjustable to 5000 psi. Because of its exceptional performance, this relief cartridge should be considered for applications where fast response, dirt tolerance and leakage are critical. Examples of this type of application would include overshoot protection of fixed and variable volume pumps and shock protection of cylinders and motors.
Design Concepts and Features
- Maximum leakage is 10 drops/min. at reseat
- Reseat equals 90% of cracking pressure
- Ability to operate more reliably in contaminated applications
- Not recommended for repeated adjustment because of high adjustment effort.
