Original Masoneilan Booster Relays Model BR200 / BR400 4 spool hydraulic control valve

Masoneilan Model BR200 and BR400 pneumatic booster relays offer high capacity air volume boost for fast and consistent dynamic control-valve system response. These devices offer a 1:1 input to output ratio with a maximum supply and signal pressure of 150 psi (10.3 bar). The BR200 and BR400 relays also include an integrated internal bypass valve for sensitivity adjustment and dynamic response optimization. Integrated filters in both the supply and signal ports feature stainless steel components and corrosion resistant finishes for a durable assembly.

Features And Benefits

• Flow sensitivity adjustment allows optimization of the system dynamic response for improved efficiency and safer operation in key pneumatic control valve applications
• Corrosion-resistant design and wide temperature range offer the flexibility to accommodate a variety of operating environments and conditions
• Provides short stroking times and consistently stable operation that results in stable process loop.
• Filters on both the supply and signal ports provide extra protection against contamination resulting in more-stable performance over a longer product life.
