DOWNSTREAM PRESSURE REGULATING VALVE
DOWNSTREAM PRESSURE REGULATING VALVE-SERIES 600
Downstream Pressure Regulating Valve is self contained, self
Operated control device, which automatically reduce a higher inlet
pressure to a steady lower downstream pressure regardless of
changing flow rate and varying inlet pressure. It utilizes energy
from the controlled system.
The regulator operates on the simple principal of force balance. A
Downward opening force is exerted by the actuator spring, which is
balanced by the upward force exerted by the controlled outlet
pressure acting below the diaphragm. Any drop in controlled outlet
Pressure due to consumption of Fluid, disturbs the force balance
and due to spring force diaphragm and stem move down pushing
the valve plug away from seat. This results in the increased flow.
The pressure reducing regulators are manufactured in a variety to
manage downstream system pressures in low, medium, high flow
application; model features a diaphragm/Piston type or
combination of both to suit different applications.
These regulators find applications throughout many industries
including the Oil & Gas, Pulp & Paper, Power Generation and
chemicals processing industries etc.

Design Features
- Models are available for Steam, air, gas or liquid service with internal or external sensing.
- Reduces higher inlet Pressure to a constant lower outlet pressure.
- Moulded sensing diaphragm provide a good proportional band and registration of outlet pressure on the diaphragm allows excellent control sensitivity.
- Glandless Construction where positive zero gland leakage is required, the design scores over conventional solutions such as Bellow seal etc., as the gland itself is eliminated and hence there can’t be gland leakage. Glandless construction eliminates hystersis, resulting in improvement of sensitivity and repeatability of the valve.
- Outlet pressure is accurate over wide range of flow.
- Pilot-Operated main valve is not subjected to pressure fall off Characteristic of direct-acting PRV’s.
- Outlet pressure is adjustable over complete range of control spring.
- Operates automatically off line pressure.
- Heavy-duty, nylon-reinforced diaphragm.
- Round-shaped, soft seat seal provide drip-tight class VI closure.
- Diaphragm assembly guided top and bottom.
- Throttling seat retainer for flow and pressure stability.
- Easily maintained without removal from the line.
- Pressure adjustment by single adjusting screw.
- Replaceable seat ring.
- Range of Body & Diaphragm material combinations to meet majority of requirements.
- IBR certification in From III C available.
- Designed ruggedly to withstand shocks.
- Simple and economic design.
Quality And Performance Guarantee
- Produced with Quality Systems accredited to ISO 9001: 2008 by Bureau Veritas.
