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.

Moisture Absorbing Breather Vents

Keep moisture, dirt, and debris from entering your oil reservoirs. The silica gel inside these breather vents absorbs moisture from the air, preventing rust from forming inside your tanks. The gel changes from blue to pink as it becomes saturated, letting you know it needs to be replaced. A second filter blocks dust and other particles from getting inside. These breather vents allow air to flow in and out of your lubrication system, keeping excess vacuum or pressure from building up in cylinders, gear boxes, and tanks.

Nylon and Polycarbonate Body—NPT Male

Breather vents with a plastic body are clear, so a quick glance will tell you if the gel is saturated. Unlike steel versions, which can be rebuilt, the entire unit must be replaced when fresh gel is needed.
