Threaded Precision Flow-Adjustment Valves with Gauge Ports

With a gauge port on each side of these valves, you can install two pieces of instrumentation equipment to simultaneously monitor multiple media properties without interrupting flow. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Valves 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 valve 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 valve with a difference of 1 psi between the inlet and the outlet.

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.

High-Pressure Threaded Precision Flow-Adjustment Valves with Vent Ports

Also known as block and bleed valves, these have two vent ports to isolate pressure gauges, switches, and other components in high-pressure systems for maintenance, calibration, and sampling without interrupting the process. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. All valves have metal-to-metal seats that resist temperature fluctuations. Body is 316 stainless steel for excellent corrosion resistance. Valves have a nut that can be tightened to compress the packing if it leaks.

Threaded Precision Flow-Adjustment Valves with Vent Port


Female × Female	Female × Male

Also known as block and bleed valves, these have a vent port that allows you to remove instrumentation equipment attached to the valve without depressurizing your line. Turn the handle to shut off flow and remove the vent port plug to drain liquid trapped in the valve. Valves adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

316 Stainless Steel Body—316 stainless steel valves are more corrosion resistant than steel valves.

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 valve is completely closed.
