Fairchild 4500 series Volume Booster pneumatic control element Valve 4514AU

Model 4500 Pneumatic Volume Boosters are popular due to their rugged design and high flow capacity in an economical package. In its pilot operated regulator design, the M4500 handles up 250 psig, [17.0 BAR], (1700 kPa) supply pressure and has five available signal to output ratios to meet most control element requirements.

• Flow capacity of 150 SCFM (255 m3/HR) - extremely fast and responsive operation
• Five signal to output ratios - versatility to meet most control element requirements
• Control sensitivity of 1" water column allows use in precision applications
• Soft supply and exhaust valve seats minimizes air consumption
• Separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
• Optional remote feedback port minimizes pressure drop at final control element under flow conditions
• Optional adjustable by-pass needle valve (includes bubble tight exhaust valve) - allows tuning for optimum dynamic response (1:1 ratio only) and cycle free operation with valve positioners
• Certification for use in all Canadian territories and provinces
• 4514A, 4524A, 4534A, 4544A, 4554A, 4516A, 4526A, 4536A, 4546A, 4556A
