Flow-Control Orifices for Chemicals
- For Use With: Air, Ammonia, Sodium Hydroxide, Beverage, Carbon Dioxide, Diesel Fuel, Water, Oil, Ethylene Glycol, Food, Hydrochloric Acid, Kerosene, Liquid Carbon Dioxide, Methanol, Soap Solutions, Methyl Ethyl Ketone, Mineral Spirits, Natural Gas, Oxygen, Nitric Acid
- Max. Pressure: 120 psi @ 75° F
- Temperature Range: 40° to 140° F
Made of PVC, these orifices have excellent resistance to a wide range of corrosive chemicals. Also known as flow restrictors and precision orifice valves, they are used to throttle, vent, bleed, or regulate the flow of liquids and gases. They automatically adjust to changing inlet pressure to maintain consistent outlet flow.

Compact Threaded On/Off Valves for Chemicals
For chemical-processing applications in confined areas, these valves have a low-profile handle to fit in tight spots. A rubber seal and a plastic body stand up to aggressive, corrosive solutions.
CPVC valves resist heat up to 195° F, so they’re the best choice if your system connects to a heater.
Full-port valves do not restrict flow. Standard-port valves slightly restrict flow.
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.

Threaded Gradual On/Off Valves for Cryogenic Liquid
- Valve Type: Gate
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Natural Gas, Liquid Methane, Liquid Nitrogen, Liquid Oxygen
- Packing Material: PTFE Plastic
- Specifications Met: ASME B31.3, CGA G-4.1, MSS-SP-80
Built to handle the extreme cold of liquid gases, these bronze valves are ideal for liquid carbon dioxide carbonation systems, liquid nitrogen coolant systems, and other cryogenic applications. They’ll also work with liquified natural gas and liquid oxygen. They’re cleaned and bagged to meet CGA G-4.1 for oxygen service. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops.
The handle raises as these valves open and lowers as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem. They have a threaded union stem housing, so you can separate the stem from the housing while the valve is inline. That means you can complete maintenance tasks, such as packing the stem, without taking apart your whole setup.

Pipeline Fluid Blockers
Also known as pipe blinds, these fluid blockers fit between two flanges to stop flow, so you can work downstream without draining the system.
Paddle blinds slip between the flanges to temporarily block flow.
304 stainless steel blinds resist corrosion better than steel blinds.
