Direct Activated Pressure Reducing Valve with Pressure Gauge

The direct acting pressure reducing valve reduces inlet pressure to the required outlet pressure through adjustment. It relies on the energy of the medium itself to automatically stabilize the downstream pressure. From a fluid mechanics perspective, it acts as a throttling element with variable local resistance. By changing the throttling area, the flow velocity and fluid kinetic energy are altered to create pressure loss for pressure reduction. Its control & regulation system balances downstream pressure fluctuation with spring force, maintaining stable outlet pressure within a certain error range.

Working Principle

The pressure reducing valve operation is controlled by its control chamber, which connects to downstream pressure via pressure sampling holes. When downstream pressure fluctuates, the control chamber drives the piston up and down to regulate pressure and keep it stable. A pressure gauge is equipped to display the outlet pressure in real time.

Features

• All valve components are made of CF8M stainless steel, with outstanding corrosion and wear resistance for robust performance and long service life.
• Adjustable throttling area changes flow velocity and fluid kinetic energy to realize pressure reduction. The control system balances downstream pressure fluctuation with spring force to keep pressure constant.
• Pressure balanced design minimizes the impact of inlet pressure fluctuation on outlet pressure. The outlet pressure can be set according to working conditions, and the fully open position relates to the adjustable pressure range and set pressure.
• Hybrid piston-and-diaphragm structure extends service life.
• Compact structure, quick response and accurate pressure regulation.

Application

Suitable for water, weak acids, weak alkalis and other liquids. Widely used for pressure regulation in fluid pipeline systems to stabilize outlet pressure.
