Siemens Moore 61 Series - Pneumatic Volume Booster

The Siemens Moore Series 61 Pneumatic Volume Booster Relays reproduce pneumatic signals in a 1:1 ratio for applications where input isolation or increased flow capacity are required. Various models are available to meet a wide range of requirements.

Valve Service:
Model 61H High-Capacity Booster Relay: The Model 61H High-Capacity Booster Relay was designed to improve the stroking speed of large diaphragm valves. As such, it incorporates a stabilising bypass needle valve between the input and output, eliminating the need for an externally piped bypass.

Model 61VH High-Capacity Booster Relay: The Model 61VH High-Capacity Booster Relay was designed for use on control valve actuators that require very fast stroking speeds. As such, it incorporates a stabilising bypass needle valve between the input and output, eliminating the need for an externally piped bypass. Both 61H and 61VH feature a stabilising bypass needle valve between the input and output, which eliminates the need for an externally piped bypass.

Pneumatic Control:
Model 61L Moderate Accuracy Booster Relay: The Model 61L Moderate Accuracy Booster Relay combines moderate accuracy with a moderate capacity (approximately 4.5 scfm output at 9 psi). Like the Model 61H relay, this instrument is used primarily in straight forward valve booster applications.

Model 61F High Accuracy Booster Relay: The Model 61F High Accuracy Booster Relay via the sensitive preformed diaphragms in this relay provides greater accuracy in 1:1 transmission. Its output capacity is about 1/4 that of the Model 61L. As such, it is suitable for use in measuring circuits.

Model 61FE Booster Relay: The Model 61FE Booster Relay is similar to the Model 61F; however, it also includes a 1/8" NPT connection for those applications where a tapped exhaust is required.

Some benefits of the Siemens Moore Model 61 are:

• Force-balance principle produces a proportional output for pneumatic circuit flexibility
• Built-in stability needle valve on the 61H minimises piping needs
• Improved valve stroking speed for better process control
• Epoxy powder coating provides improved corrosion resistance
• Accurate 1:1 signal relay provides pneumatic circuit design flexibility
