Various type of pressure control valves are available, from relief valves to pressure switches, to control the pressure at suitable level in the hydraulic system.
Low Noise Type Pilot Operated Reliel Valves
Pilot operated relief valves here have been particularly developed as low noise type. To protect the pumps and control valves from an excessive pressure, the valves are used to control the pressure in the hydraulic system to constant level. The remote control and unloading can be done by using the vent circuit.

Proportional Control Valves are controlled by electronic Amplifier control boards, and are commonly called electro-hydraulics. These Proportional Valves control direction and the amount of fluid flow or can control the amount of pressure within a system.
Electro-hydraulic controls are especially useful in situations where system speed must be tightly controlled, or where ramping up and down is needed to avoid sudden starts or stops. Electro-hydraulics also provides precise control in applications where hydraulic pressure must be built up steadily.
Continental Hydraulics Proportional products can help increase production and reduce down time by minimizing the shocks that occur from sudden changes as compared to standard components.
In conjunction with precision valves, Continental Hydraulics provides Electronic Control Amplifier Cards. These Amplifiers come in a variety of mounting styles, signal conditioning, PWM and Dither, Acceleration and deceleration limiting and current sensing circuitry to work with and accurately control proportional products whether in open or closed loop systems.

The PLC series auxiliary valves are direct-acting, factory-set pressure relief valves of the cartridge type that can be supplied with or without a threaded plug. They can also be supplied with housings to facilitate in-line installation. PLC valves are intended primarily to act as combined pressure-relief and anti-cavitation valves - otherwise known as port relief valves - in the service ports of our directional valves. However, they can also be used to advantage in other situations where pressure relief valves in this size range are required. Indeed, PLC cartridge valves are purchased in great quantities by several of the world%u2019s leading pump and transmission manufacturers.

The 289 Series relief valves are spring-loaded throttling relief valves used downstream of pressure regulators to protect the downstream system from overpressure. A smooth throttling action minimizes pressure surges in the system during relief operation. The 289 Series relief valves are ideal for low-pressure settings due to the increased sensitivity provided by a large diaphragm area. The 289 Series relief valves are designed for pressure control; they are not ASME safety relief valves.

The Brand, adjustable pilot operated relief valve maintains the same cracking pressure at low and high flows. As the pressure setting is exceeded a poppet type relief opens and allows a small pilot supply of fluid to escape a chamber at the end of the main spool. The escape of pilot supply causes the main spool to shift and thus opens a passageway which allows the main volume of pressurized fluid to escape to tank without passing over the poppet type relief. The higher the pump output the farther the spool shifts over to enlarge the opening to tank.

The Brand, shuttle valve has two inlet ports and one outlet port. The purpose of the shuttle valve is to accept flow from the inlet with the higher pressure and to route it to the outlet, while keeping the inlet flows isolated from one another. We manufacture shuttle valves in two sizes SHV50C and SHV25. The SHV50C has 1/2" NPT ports, capable of 0-15 gpm (0-57 lpm) and a peak pressure drop of 15 psi (1.0 bar). SHV25 has 1/4" NPT ports, capable of 0-5 gpm (0-19 lpm) and a peak pressure drop of 50 psi (3.4 bar).

These 2/2-way ball seated directional valves are either directly or pilot actuated by a solenoid. With the directly actuated version the valve passage is opened or closed by a cone whereas with the piloted a piloting duct of a stepped piston is opened or closed generating a pressure difference at the opposing facial areas of the piston forcing it in the open or closed position.
Type EMP is a proportional valve, acting like a throttle but with zero leakage in blocked position. The dampened version will increase the switching time for on/off controls (hydraulic ramp). The wet armature solenoids for the valve actuation are pressure resistant, where all moving internal parts are flushed by oil.
There is a wide range of connection blocks either for pipe connection or for banjo bolt mounting, which may feature optional elements such as drain valve, by-pass throttle, pressure switch, 2-way flow control valve etc.
