Ultralow Pressure Regulator
Ultra Low Pressure Regulators are used where very low (mmWC) and stable output pressures are desired.

These regulators are very sensitive to incoming pressure fluctuations. A very large diaphragm area to orifice ratio provides very stable control in ultra low-pressure range.

OPTIONAL
Different materials of construction like Brass, S.S. 304/ S.S. 316 with
Seals of Viton or Nitrile available.

Backpressure Regulator
Back Pressure regulators are ideally suited for Pneumatic circuits which have to have over pressure relief or pressure regulation through bypassing excess pressure. Large diaphragm area increases sensitivity and decreases differentials between set release pressure and rest sealing pressure. Pilot pressure operated regulators also available on request.

a) Special material of construction such as S.S. 304/ S.S. 316, Brass & Bronze with     seals of nitrile and viton available.
b) Available for higher working temperature (up to 250 °C)

3" Regulator
3" Regulators are specially designed for high flow applications of large compressed air installations. These regulators provide stable output pressures at high flow with minimum pressure droop. Ideal for 3" lines where differential pressure between inlet and outlet is low. Suitable for flows upto 600 Scfm.

Standard body construction is graded C.I. body with brass and S. S. Internals. Diaphragm is nylon-reinforced nitrile. Seals are nitrile. Balanced valve disc gives instantaneous response.

Maximum inlet pressure is 150 PSI (10.6 Kg/Cm2) for C.I. body. For High pressure C.S./S.S. 304 or S. S. 316 are also available. Output pressure can be 0-60 PSI (4.2 Kg/Cm2) or 0-150 PSI (10.6 Kg/Cm2). End connections can be flanged or threaded.

Pilot type regulators also available as option

Pilot Pressure Regulator
These are basically pressure regulator to reduce and regulate the output pressure from main line. The output pressure will be proportional to signal pressure. The signal pressure can be from another regulator, transducer or instrument.

Such construction facilitates mounting of the pilot regulator in remote place such as at height inside, out into field and get a controlled output pressure from main line by providing a signal which is regulated to desired pressure.

Added advantage of such a regulator is that output pressure range can be increased up to 90 % of input pressure. Also, by replacing regulating spring with a regulated pressure signal, hysterisis, which is an inherent characteristic of spring-operated regulator, can be eliminated.

SIZES AVAILABLE
1/4", 3/8" and 1/2" BSP (F)/NPT (F)

MATERIAL OF CONSTRUCTION

Volume Booster
Volume Booster are widely used in instrumentation where volumetrically weak signal is not sufficient to directly operate valve or other equipments. When the supply pressure is connected to the volume booster and signal pressure is applied the resultant output pressure will be in 1:1 proportion to the signal pressure but the volume will be much larger, which can be directly used to operate valves or any other equipment.

SIZES AVAILABLE
1/4", 3/8" and 1/2" BSP (F)/NPT (F)

MATERIAL OF CONSTRUCTION
Body: Extruded Aluminum
Bonnet: Aluminum
Internals and Trims: Brass and S.S.
Seals: Nitrile

Automatic Signal Relay
Automatic Signal Relay is designed to automatically lock-up the transmitted signal when the supply pressure fails. The lock-up will occur when the supply falls to 2 PSIG above signal pressure. When the supply pressure is restored, this model lock-up relay will automatically reset and assume normal operation.

All of the internal flow passages are full standard 1/4" schedule 40 I.D. that give this model relay an unrestricted flow. This high flow characteristic allows this model to be used in series with a controller or I/P transducer to feed a signal directly to a valve.
