Features: Our hydraulic Two way Throttle valves is long terms, and precisions machined from carbon steel. Hydraulic flows Control valves use for fluids, air, gas, oil and fuels. Works for multiple applications and industries, including hydraulics, pneumatics, plumbing. The hydraulic flows restrictor operates at a standardized flows rate and offer a highly controlled flows of hydraulic fluid. The high flows control valves accurately controls the speed of hydraulic cylinders. Our Hydraulic Control valves maintains a constant flows rate and is ideal for applications that require calibration. Can safeguards pumps, actuators, and compressors from damage. Its fast acting operate significantly reduces downtime, improving overall operational output.
