Bronze two-way globe valve, straight-through body, Cv 7.3, 400 psi rating

Johnson Controls Inc

Johnson Controls VG7441LT two-way globe valve Cv 7.3 400 psi

SKU CH-4Z4V-NED8S

A two-way bronze globe valve with a Cv of 7.3 rated for 400 psi hydronic service

  • Bronze body resists corrosion for long hydronic service
  • Two-way straight-through pattern simplifies piping layout
  • Cv 7.3 provides precise flow control for heating loops
  • ANSI Class IV seat limits leakage to tight tolerance
  • Rated to 400 psi for demanding commercial systems

Hydronic Globe Valve Cv 7.3

The Johnson Controls VG7441LT is a two-way bronze globe valve for hydronic systems. It provides straight-thru flow control with a 7.3 Cv coefficient. The valve body is rated for 400 psi maximum allowable pressure. It meets ANSI Leakage Class IV for tight shutoff.

Suitable for hydronic control loops

This valve suits installations needing a two-way bronze body with spring-return actuator action. It is not for applications requiring three-way mixing or diverting configurations. Buyers needing different Cv values or actuator voltage specifications should look elsewhere.

Cv 7.3 flow coefficient

The 7.3 Cv rating determines the flow capacity at a given pressure drop. Match this value to your system design calculations for correct sizing. The 400 psi pressure rating and Class IV leakage define the operating envelope.

Questions about this item

Should I choose the VG7441LT with a Cv of 7.3 or look for a different Cv value?

Select the 7.3 Cv when your design flow rate and available pressure drop match that coefficient; a higher Cv would open less for the same flow, while a lower Cv would need more pressure drop.

What does the 400 psi pressure rating mean once the valve is installed in a hydronic loop?

The body is tested to hold 400 psi static pressure, so the valve will not rupture at normal hydronic system pressures well below that limit.

How does the ANSI Class IV leakage rating affect shut-off performance on this two-way globe valve?

Class IV allows a small, measurable leak rate past the seat; the valve is not bubble-tight, so expect minimal seepage when fully closed.
