Flow-Adjustment Valve Manifolds for Sealed Systems
A sealed design prevents contamination in dirty and dusty environments. Use these manifolds to serve multiple lubrication points from a single location. Adjust the flow to individual lubrication points by turning the dial on the corresponding valve. Each valve can be removed for cleaning without disturbing the rest of the system. They can be used with any oil grade. Flow rate depends on temperature. They have NPTF (Dryseal) threads, which are compatible with NPT threads.

Flow-Adjustment Valve Manifolds for Vented Systems
For use in clean environments, these manifolds have multiple air vents that keep pressure balanced. Use them to serve multiple lubrication points from a single location. Adjust the flow to individual lubrication points by turning the dial on the corresponding valve. Each valve can be removed for cleaning without disturbing the rest of the system. They can be used with any oil grade. Flow rate depends on temperature. They have NPTF (Dryseal) threads, which are compatible with NPT threads.

Metering Valves for Oil-Dispensing Pumps
Use these valves with manual and electric pumps to dispense different amounts of oil from multiple lubrication points. They have a check valve to prevent backward flow. To connect to tubing, use a compression nut and sleeve (sold separately).
Flow rate trade number indicates the relative amount of oil each valve delivers. For each increase in trade size, the amount of oil delivered approximately doubles. For example, 0 delivers twice the amount of oil that 00 delivers. In a system with two lubrication points, the lubrication point connected to 0 will receive 2/3 of the oil dispensed, and the lubrication point connected to 00 will receive 1/3 of the oil dispensed. In general, valves with lower relative flow rates are better for cycling systems; valves with higher relative flow rates are better for continuous recirculation systems.

High-Pressure Threaded Precision Flow-Adjustment Manifolds
- Valve Type: Needle
- For Use With: See table
- Seal Material: Fluoroelastomer Rubber
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 seats resist temperature fluctuations.
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
- Valve Type: Needle
- For Use With: Water, Oil, Air, Argon, Helium, Krypton, Neon, Xenon
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.
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.

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 valves are more corrosion resistant than steel valves.
