Ball Type Check Valve

Ball Type Check Valve is a type of valve which only permits flow in one direction. Ball Type Check Valves are often designed for safety reasons, to prevent back flow and to ensure that someone operating a system knows which direction fluids and gases are flowing in. Ball Type Check Valves can also be used for tasks like creating leak tight seals, which can be an important safety or convenience future. Ball Type Check Valves are also used for the routine task of directing fluids or gases efficiently through a system.

Solenoid operated valves

Solenoid operated valves differ from manually and hydraulically
pilot-operated valves in that they are electrically controlled as
opposed to using complex mechanical linkages or bulky hydraulic
pilot lines to actuate the valve. 2 Position 2 Way Solenoid Valves

Counterbalance valves

Cartridge Counterbalance Valves are a regulating mechanism on valve-powered cylinders, such as those on electrical repair trucks. The counterbalance valves serve to limit the amount of fluid change within the flange, thus preventing sudden changes in pressure and resultant instability.
Cartridge Counterbalance Valves work by reacting to the weight of the load as that weight is translated into pressure on the pump cylinder.
Hydraulic Cartridge Counterbalance Valves are used in hydraulic systems working with overriding (running-away) or suspended load. They are designed to create backpressure at the return line of the actuator to prevent losing control over the load.

Relief Valves RV-08

Cartridge Direct Relief Valves are spring-loaded throttling relief valves used as downstream  pressure regulators to protect the system from overpressure. A smooth throttling action minimizes pressure surges in the system during relief operation. Relief Valves RV-08 are ideal for low-pressure settings due to the increased sensitivity provided by a large diaphragm area. Relief Valves RV-08 are designed for pressure control
