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.

Flow control valves
MRP / MVR
These cartridge flow control valves provide pressure- independent division of a flow of oil into a constant flow and a surplus flow. Inlet flow maximum 40 l/min.
MTCA
These valves provide pressure-independent division of a flow of oil into a constant flow and a surplus flow. The two part-flows can be pressurized independently of each other. With integral pressure relief function.
MTKA
These valves provide pressure-independent division of a flow of oil into a constant flow and a surplus flow. The surplus flow can be pressurized and can therefore be routed to an additional actuator.

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.
