Type 40- T40 Adjustable Regulator
The Bellofram Precision Controls Type 40 is an adjustable air pressure regulator for instrumentation and general industrial pneumatic systems. It supports supply pressure up to 250 psig and combines a soft-seat valve stem, aspirator, and 60-mesh stainless steel screen to provide stable downstream pressure, low droop at higher flow, and protection from foreign particles. The self-relieving regulator can be pipe, panel, or bracket mounted and is used with pilot-operated controllers, instruments, air chucks, spray guns, air cylinders, actuators, and other pneumatic equipment.
Features:
- Superior regulation characteristics
- Rugged, corrosion-resistant construction
- Low cost
- Excellent stability and repeatability
- Self-relieving
- Low droop at high flow
- Several mounting options
- Pilot-operated Controllers and Instruments
- Air Chucks
- Air Spray Guns
- Air Cylinders and Actuators
- Industrial Pneumatic Systems and Equipment
