High-Pressure Threaded Precision Flow-Adjustment Valve Manifolds
 |
Often attached to differential pressure gauges to measure liquid level in tanks, these manifolds have two isolation valves with a pressure-equalizing valve between them. To isolate your differential pressure gauge for maintenance or calibration, shut off flow on both sides and equalize pressure in the manifold. All manifolds have a 316 stainless steel body for excellent corrosion resistance.
Metal-to-Metal Seat—Metal-to-metal seats resist temperature fluctuations.
Bubble-Tight Soft Seat—Bubble-tight soft seats provide a tighter seal than metal-to-metal seats when the manifold is completely closed.
Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open manifold with a difference of 1 psi between the inlet and the outlet.
