ControlAir’s Precision Pressure Regulators, Filter Regulators, Volume Boosters, Air Relays and I/P Transducers help ensure precise pressure adjustment for instrumentation and process control in the oil and gas markets. These demanding applications require accurate and repeatable pressure regulation, sometimes under extreme conditions. ControlAir’s family of Stainless Steel and NACE units provide longer life in offshore and other harsh environments.
 

Precision type-100 Pressure Regulator
Dependable, Highly Accurate Pressure Regulation to 0.1%. The Type 100 is a high precision, multi-stage pressure regulator. This pressure controller provides the highest level of regulation accuracy and repeatability available. 

Precision type-100 Pressure Regulator

The Type 100 is ideal for applications that call for the utmost of control and maximum stability under variable operating conditions. A stainless-steel measuring capsule is used as a sensing element to activate the high gain servo balanced control mechanism in which the main valve is controlled by a pilot valve. This allows for greater accuracy and eliminates many of the problems associated with conventional regulators using range springs and diaphragms.
 

Type 700 High Flow Pressure Regulator
The Type 700 is designed for applications that require high flow capacity and accurate process control. A poppet valve which is balanced by utilizing a rolling diaphragm insures a constant output pressure even during wide supply pressure variations. Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the air supply in accordance with the flow velocity.

Type 330 Air Filter Regulator
The Type 330 Instrument Air Filter Regulator is designed to provide clean, accurate air pressure to instruments, valves, and other automatic control equipment in a lightweight, compact housing. This quality instrument is constructed of durable materials that will provide long lasting corrosion resistance in harsh industrial environments. The Type 330 AFR features either a 40-micron or 5-micron filter to allow for more precise filtration.

The Type 330 Filter Regulator with Automatic Drain automatically flushes out condensate waste liquid when a change in air flow occurs or when the supply pressure is reduced. The low maintenance Automatic Drain helps prolong the life of the regulator and filter by preventing corrosion on the bottom of regulator and reducing the load of the filter.

Options and features (see specification tab for full list):

¼” and ½” port sizes
40- or 5-micron filter
Auto-drain capabilities
Low temperature option: down to -62°F

Type 330 Air Filter Regulator

Type 1230 High Pressure Gas Regulator
The Type 1230 is a pressure-reducing, direct-operated regulator suitable for use with compressed air, natural gas, sour gas or an assortment of other inert gases. The Type 1230 utilizes a similar design to the Type 1227 but provides a much broader offering of output pressure ranges and valve disk materials. The Type 1230 is available with output pressures that span from 50 psi to 500 psi making it suitable for use across a vast range of industries and applications, especially those utilizing regulators in series for controlled pressure reduction across multiple stages.
 

Features
• Guarded against unwanted set point adjustment with tamper-proof cap
• Trim can be replaced without disconnecting regulator from the system
• Can be re-arranged into multiple orientations for difficult installations with limited
maneuverability
• NACE MR-0175 configurations available. (Ask our sales team about CRN availability)
• Assembled and Tested in the USA

Type 6100 High Flow Capacity Volume Booster
Rapid Stroke Capability in a Rugged Aluminum Casing

The Type 6100 aluminum volume booster is a 1:1 signal to output relays that is utilized in applications that require high forward airflow and exhaust capacities. Typically, they are used to increase the throttling speed of large volume valve actuators. They are suitable for either diaphragm or piston actuators. A fixed dead band and adjustable bypass valve combine to allow small incremental downstream adjustment without opening the main booster valve. The bypass valve is used to adjust dynamic response to provide stable operation over a wide range of actuator sizes.  Negative Bias adjustment (up to -4 psi) is available to “zero” downstream pressures when using standard signal pressure ranges.

Type 6500/6600 Stainless Steel High Flow Capacity Volume Booster
Rapid Stroke Capability in a Rugged Aluminum or Stainless-Steel Casing

The Type 6500 aluminum and Type 6600 stainless steel volume boosters are 1:1 signal to output relays that are utilized in applications that require high flow capacity. Typically, they are used to increase throttling speed of large volume valve actuators. They are suitable for either diaphragm or piston actuators. A fixed dead band and adjustable bypass valve combine to allow small incremental downstream adjustment without opening the main booster valve.
