Check valves are used in a variety of industries, systems, and services, including: • pumps and pumping equipment Counterbalance Valves Parker counterbalance valves are screw-in type cartridge valves that control the pressure at an actuator controlling its motion. A March 2018 post on the company’s blog discussed these components and how proper sizing can prevent the “chattering” with which they’ve sometimes been associated. Discon- nect flanges at ports I and 2 and remove the valve from the piping. It’s also one of the most common causes of check-valve failure. Sometimes this chatter is caused by the design of the cylinder, not the counterbalance valve. A typical circuit application for a counterbalance valve contains a pump, directional control valve, and an actuator. going to yard the 3 port PO checks and use probably a counterbalance valve or maybe a 4 port vented po check. © 2020 Efficient Plant. The result of hysteresis is bounce, loud chatter, or high-pitch squealing. Replaced the water pump, mounting studs and gasket, fan belt, and upper and lower radiator hoses. Unfortunately, this approach completely ignores the fact that check valves are sensitive to flow conditions. Consider the following when troubleshooting relief valves because they have excessive noise or chatter: • Oil viscosity is too high. • Line pressure has excessive return.
