Stainless Steel Pneumatic Relays and Volume Boosters
from ControlAir LLC
The Type 6000 Volume Booster is a one-to-one signal to output relay that, when used with a positioner/actuator, is designed to increase the stroking speed of control valves. A large input signal change to the volume booster delivers high volume, fast action throttling control. An integral bypass... [See More]

Set to trip on either an increasing or decreasing control signal, the Mite 70 will vent one port to atmosphere while it locks up the pressure in a second line. The tripped position is then held indefinitely until the control signal is restored and a manual reset button is pushed. The trip point is... [See More]

The Mite 85 allows you to establish two adjustable trip points that control flow through a 3-way valve. An increasing signal that exceeds the high trip point will open "I" port to "H". A decreasing signal pressure that drops below the low trip point will vent port "H". This switching action is... [See More]
