Typical logic circuits employ differential area, 2-way poppet valves, where the combined pressures at all ports, plus or minus the spring forces, determine whether the valve is open or closed. On the other hand, whether the valve is open or closed determines the combination of pressures ... so where do you begin?
Sun's 4-port balanced logic switching elements take the guesswork out of logic circuitry. These 2-way poppet valves, offered in either normally open or normally closed configurations, are unaffected by pressure at the work ports. Available in four sizes with flow rates from 60 to 480 litres per minute. All ports can accommodate 35 MPa. Twenty-five different functions are available.

Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
