Electrohydraulic inverse proportional pressure relief valve for fan drives

July 13, 2021 By Mary Gannon

Sun RPEI electrohydraulic valve

The RPEI electrohydraulic inverse proportional pressure relief valve is a new high-capacity pressure control that provides smooth, precise speed control in fan drive applications. Designed for use in fan drive applications, the RPEI combines attributes of an electro-proportional adjustable pilot stage valve and a high-capacity main stage valve to provide precise pressure control inversely proportional […]

By Josh Cosford, Contributing Editor The line that separates the performance of servo and proportional valves has blurred in recent years. Some may consider a servovalve to be any valve capable of accurately positioning your actuator with closed-loop control. However, in everyday hydraulic circles, many industry professionals describe a servovalve as a valve with a […]

Double selector six-way hydraulic valves provide flow direction to two circuits

May 13, 2021 By Mary Gannon

Doering double six-way selector valve

The DS-Double Selector hydraulic valve from Doering is a two position, six-way, double selector valve which directs the flow of hydraulic fluid to two separate hydraulic circuits within your hydraulic system. This flow divider valve allows the operation of two double-acting cylinders with one four-way control valve or four single-acting cylinders with two-three-way control valves. It […]

Proportional flow control valves for every application

April 26, 2021 By Ken Korane

In hydraulic systems, proportional flow control valves ensure that flow rates remain virtually constant. In doing so, they have to meet a large number of performance criteria that extend beyond their core function. According to engineers at Bucher Hydraulics, manufacturers and operators of mobile machines are increasingly placing a special emphasis on energy efficiency. Flow […]
