Type 110 Large Forward & Exhaust Flow Air Pressure Regulator

Brand: Marsh Bellofram Group of Companies

The Type 110 Large Forward and Exhaust Flow Air Pressure Regulator combines the proven technology of the Type 10 regulator with the large pneumatic booster of the Type 79 Relay.

The result is a precise, crisply responding regulator that can achieve very large forward and exhaust flows. Forward to reverse flow offset is minimized by the capsule operated, servo-control system located in the upper portion of the regulator.

This servo-control system supplies a pilot pressure to the large integral pneumatic booster. The large supply and exhaust orifices of the integral booster enable this regulator to produce very high forward and exhaust flow rates. Few regulators can offer this combination of sensitivity and large flow capacity.

As with all of the Type 10 regulators, the stainless steel measuring capsule is the “heart” of the Type 110 Pressure Regulator. Originally developed for sensitive aircraft altimeters, this precision-sensing element provides the energy to activate the servo-control mechanism.

It provides greater regulation and accuracy while eliminating the problems usually encountered with range springs and conventional diaphragms. Because of the balanced supply valve in the integral pneumatic booster, the Type 110 can work with higher supply pressures (250 PSIG) than many other regulators.

The Type 110 was developed specifically for use with Air Balancing Systems or Zero-Gravity Arms. Such systems require very small forward to reverse flow offsets for smooth operation. The precision regulators that can achieve the sensitivity requirements do not typically possess the forward or exhaust capacity to handle large balancing arms or cylinders.

The Type 110 does not have this limitation. It is ideal for use in any application where precise regulation of pressure is required along with high flow or high exhaust capacity.
