High Flow Capacity in a Rugged Casing
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 valve provides system stability while allowing normal positioner airflow and normal valve actuation with small input changes. If the volume booster is to be used for on/off control valves, the bypass valve can be closed to optimize stroking speed. The Type 6000 is available in aluminum or 316 stainless steel construction.
Pilot operated, multi-stage 1:1 relay
The Type 200 Precision Air Relay is a pilot operated, multi-stage 1:1 relay with a positive and negative bias adjustment capability. It accurately reproduces a signal pressure plus or minus the bias setting with consistent reliability. Output control and stability are maintained through a high gain servo balanced control mechanism which is activated by a highly sensitive stainless steel measuring capsule.
Reliability for fail in place applications
The ControlAir Type 250 Lockup Air Relay is a reliable unit for fail in place applications of control valves when air supply drops below acceptable pressure levels. Valve or damper position is maintained by capturing air pressure inside the diaphragm chamber (or piston cylinder) of the actuator, when the supply pressure falls below the desired set value.
High pass or low pass pneumatic selecting relay
The Super Mite 71 will automatically select the higher or lower of two pneumatic inputs and pass it downstream while blocking the other. Capable of almost instantaneous selection, the Super Mite 71 can separate pressure differentials as low as a tenth of a psi. Although ordered as either high or low pass, the Super Mite 71 can easily be converted in the field from one to the other. The Super Mite 71 can be relied on to open or close valves when a signal pressure drops or rises past a determined value. They can also be used to prevent a valve from opening or closing beyond a critical point.
Snap-acting control relay with integral 3-way valve
The Mite 74 combines the Mite 70 control relay with a precision 2-way or 3-way valve in a single compact package. Either an increasing, decreasing or remote signal can be used to channel air as needed. The Mite 74 can also be used in combination with either of the Super Mite 71’s so that it will trip when either of two signals drops or rises beyond a set pressure. Once tripped, the Mite 74 will hold its settings until the proper control signal is reestablished and the reset button is pushed.
Snap-acting 3-way valve with two trip points
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 reversible and repeatable without having to manually reset. Use the Mite 85 to passively switch to a secondary controller in case the primary system fails.
TESCOM™ BB-1 Series high pressure, low flow, miniature pressure reducing regulator provides six outlet pressure ranges available up to 1800 PSIG [124 bar] outlet. This non-venting regulator is small and compact, weighing approximately 4 oz [113 g] in the standard aluminum construction. Also available in 316 stainless steel. Ideal for use in portable and OEM equipment.
TESCOM™ 04 Series space saving and lightweight miniature regulator offers minimal internal volume and is easy to purge which results in less retention. Ideal for use in analyzers, lecture bottles and sampling systems.
