Masoneilan Model BR200 / BR400 Booster Relays High Capacity Volume Booster Relays for control valve

Product Introduction

GE’s Masoneilan BR400 and BR200 are high capacity volume boosters for applications that require fast stroking speeds using pneumatic actuators. Stable operation over a wide range of actuator sizes can be obtained by adjusting the bypass valve on the booster to modify the dynamic response.

The models BR200 and BR400 are equally suitable for use on diaphragm or piston actuators. Features and Benefits • Flow characteristics suitable for control valves • Short stroking times with consistently stable operation for use on high-volume actuators or on very demanding stroking time control valve applications • Built-in bypass valve with locking screw to adjust sensitivity and dynamic response • Filter on the supply port to protect instrument from particles in air supply • Corrosion-resistant finish and stainless assembly hardware to permit use in corrosive atmosphere Principle of Operation The input signal pressure is applied to the upper diaphragm to produce a force that is opposed in a 1:1 ratio by the output pressure acting on the lower diaphragm through the seal plate orifice. An increase in the input signal pressure will depress the top diaphragm and open the pilot valve, allowing supply pressure to the output until the output pressure action on the lower diaphragm re-balances the forces. Conversely, a decrease in the input signal pressure allows the exhaust valve to open until the output pressure falls to the same value as the input signal pressure. A bypass valve allows a controlled flow of input signal directly to the output to obtain stable control for small or slow-changing input signals.
