BELIMO® B3 Characterized Control Valve, 1/2 Inch, FNPT, 600 psi, 0.3 Cv, AF24-SR Spring Return Actuator, 3-Way, Media: Chilled/Hot Water, 60% Glycol, Forged Brass Body, Stainless Steel Stem, PTFE Seat, Tefzel® Disc, (2) EPDM O-Rings, 0 - 250 deg F, 2.41 Inch W x 1.39 Inch H, Nickel Plated
- 90 deg rotation
- 200 psi close off
- 75 deg controllable flow range
- Thermal isolating adapter between flange and actuator
- Easy direct coupling of actuator with a single screw
- Perpendicular mounting flange and square drive head eliminate lateral forces on the stem
- Blow out proof stem with thrust bearing teflon disc and double o-ring design for long service life
- Stainless steel ball
- Vent holes reduce condensation build-up
- Forged brass valve body - no pin hole leaks
- Characterizing disc made of Tefzel® known for excellent strength and chemical resistance
- Teflon seats with o-rings provide constant seating force against the ball and reduce torque requirement
- Actuator can be mounted in four different positions
- Equal percentage flow characteristic
- Excellent control stability assured with the characterizing disc
- Cv values equal to Cv values of globe valves the same size
- The need for multiple pipe reduction is usually eliminated
- Better control prevents “hunting” of the control loop, increasing life span of actuator and valve
