BELIMO B217 3/4 2WAY CCV VALVE 4.7CV

MFR Part #: B217
SKU #: 1085915
Brand: BELIMO®
UPC: 400005940255
BELIMO® B217 Characterized Control Valve, 3/4 in, FNPT, 600, 200 psi, Forged Brass, Nickel-Plated
5 Year
For air handling units and fan coil unit on heating or cooling coils

BELIMO® Characterized Control Valve, 3/4 in Nominal, FNPT Connection, 2-Way Ways/Position, 600, 200 psi, 4.7 Cv Flow Coefficient (Cv), Stainless Steel Stem, Stainless Steel Trim, EPDM Packing, PTFE Seat, EPDM Seal, Forged Brass, Nickel-Plated, Maintenance-Free Service, 0 to 250 deg F, 2.73 in L

Belimo's unique characterized control valve (CCV) is very different. A special characterizing disc inside the valve gives it an equal percentage characteristic which is comparable with that of a globe valve of the same nominal size. The flow (the Cv value) is reduced to the required value by a combination of the hole in the ball and the shaped aperture in the disc. The increase in flow as the valve is opened is very slow and controlled.

Features

  • VAV box reheat coils and bypass loops
  • This valve is suitable for use in a hydronic system with variable flow
  • Equal percentage flow characteristics
  • A port as stated in chart B-port 70% of a to AB Cv flow rating
  • 75 deg controllable flow range
  • 0% for a to AB leakage
  • The need for multiple pipe reduction is usually eliminated
  • Better control prevents hunting of the control loop, increasing life span of actuator and valve
  • 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
  • Blowout-proof stem with thrust bearing PTFE disc and double O-ring design for long service life
  • Non-corroding chrome-plated brass or stainless ball
  • Vent holes reduce condensation build-up
  • Forged brass valve body no pin hole leaks
  • Characterizing disc made of Teflon® known for excellent strength and chemical resistance
  • PTFE seats with O-rings provide constant seating force against the ball and reduce torque requirement
  • Actuator can be mounted in four different positions
  • Chilled or hot water, up to 60% glycol fluid
