Pressure Reducing Valve
Pressure reducing valve is direct acting regulator which regulate
the downstream pressure to the adjusted point and the valve closes when the
downstream pressure rises. Suitable for Water, steam and gas up to temperature
350°c with condensate pot.
Principle of operation:
Media flows through the upstream side of valve . The Plug with stem is
connected to the actuator stem. The Downstream pressure is applied through
control line to the actuator diaphragm where it is converted into spring force.
With the set point adjuster, we can adjust spring pretension the required
downstream pressure.
When the downstream pressure increases above the set point
adjusted pressure, the valve closes proportionally to the change in
pressure.
The balancing valve have balancing bellow where the upstream
pressure act on outer surface of bellow and downstream pressure act on inside
surface of bellow. As effective area of balancing bellow is equal to seat area
the differential forces compensated so there is no effect of any changes
fluctuations in upstream pressure.
Valve sizes DN25 to DN80, class rating 150 and 300.
Simple and
Compact design.
• Upstream
pressure and Downstream pressure balancing by stainless steel bellows.
• Exchangeable
actuator and Spring.
• Screwed
seat ring.
• Flow
dividers for noise reduction.
