Snap-Shut Threaded On/Off Valves
For applications that require intermittent operation, such as spraying and washing, push or pull the lever on these valves to start flow. They spring closed when the lever is released.
Brass valves are stronger and less brittle than zinc valves for use in higher-pressure applications.
Push-lever valves are commonly used in car wash systems. However, you can’t use them as blow guns. Those with a Viton® fluoroelastomer rubber seal stand up to long-term use with harsh solutions, such as wheel and tire cleaners. Valves with a TFE plastic seat are more durable than those with a Viton® fluoroelastomer rubber seat. For even more durability, choose those with a thick spring—their spring is stronger and lasts longer than standard springs. You can install valves with a mounting stem and nut in a fixed position. Valves with offset ports come with a wand bracket to attach an upholstery cleaning wand, so they’re best for floor and upholstery cleaning equipment. Connect the bracket to the top of the offset ports.
Replace worn components on 30° elbow valves with a repair kit (sold separately).
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.

Drain Valves
Also known as stop cocks, install these valves on your tank for easy draining of air or fluid.
Inline handles can be operated from any position. The handle surrounds the drain outlet, so liquids may splash onto your hands or the handle. Side handles are out of the way of the flow, so your hand and the handle stay dry.
Valves with an external seal are for higher flow applications than valves with an internal seal. They also have a longer valve stem, so they’re less likely to introduce contaminants from exposed threads. Valves with an internal seal have shorter stems than those with external seals, so they fit shorter clearances. However, they’re more likely to introduce contaminants to the tank from debris collected on the exposed threads.
Valves with a brass body won’t corrode when venting air or draining water—even in wet or humid environments.
Brass handles won’t corrode.
Valves with a thumb-screw handle open by rolling the slip-resistant thumb screw between your fingers. Since these valves don’t have a wide handle, they fit in tighter spaces than valves with other handle styles.

Valves with a wing-nut handle give you leverage to open tight, stubborn valves that have been sealed for long periods of time. The wings on these handles face outward, so they fit tanks without enough clearance around the drain hole to fit handles with inlet-facing wings.
A spout outlet smoothly pours any draining liquid into buckets without splashing.

Valves with a wing-nut handle give you leverage to open tight, stubborn valves that have been sealed for long periods of time. The wings on these handles face inward, so they have a lower profile than outlet-facing wing nuts. A spout smoothly pours any draining liquid into buckets without splashing.

Breather Vents
Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks. You can also use these breather vents to block debris from entering equipment.
Breather vents with splash guard are good for containers that are often filled and drained; they have a guard that prevents oil from splashing out of the vent hole.
Style G has a slotted drive for installation with a screwdriver.
Style H has a Buna-N O-ring for extra protection against leaks.

Corrosion-Resistant Breather Vents
These breather vents withstand corrosion in damp environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.
Polyethylene breather vents can be cleaned with mineral spirits.
Stainless steel breather vents stand up to higher temperatures than polyethylene breather vents. Those with a Viton® fluoroelastomer O-ring offer extra protection against leaks. 316 stainless steel breather vents resist corrosion better than 303 and 304 stainless steel breather vents.

Moisture-Eliminating 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.
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. For washdown environments, select breather vents with check valves. These valves allow air to flow in and out, but close when liquids try to enter.
