Model "BV" Breather Vent Valve

Model BV12 breather vent valves are used wherever a one-way breather vent is required. Valve opens at maximum of 12" water column, and reseals tightly when pressure is released. Flow passage is equivalent to 7/32" diameter hole.

Brass body and cap, with fluorocarbon rubber disc and stainless steel spring.

Model "TV" Tank Valve

Model TV12 tank valves include a brass body, nylon cap, and standard tire core valve. They are used wherever a method of inflating a tank with a standard air chuck is required. 1/8" NPT inlet.

Model "M20053" Muffler

The M20053 muffler is available as an option on the LGM30 unloader valve, but is also great for other applications that require a silencer with high flow capabilities. 3/8" NPT inlet, 1-1/8" long. Brass body with aluminum diffuser screen.

Model "CS" Cold Start Valve

CS12 and CS25 valves bleed air from the compressor head during the first few pump revolutions, thus reducing motor starting torque requirement. These valves are especially helpful on oil-lubed pumps that may be subject to low temperatures and low starting voltages, such as a contractor unit that may sit outside overnight and be connected to a long extension cord.

The CS valve is installed into any convenient port upstream of the tank check valve. Typical installations are into a 1/8" NPT port in the check valve (CDI in-tank check valves are available with the CS12 installed as an option), into a port tapped in the head of the pump, or into a "tee" in the discharge line. With the discharge line at zero pressure, the CS valve is open. As the pump starts, air flows out the CS valve to atmosphere. As pump speed and discharge pressure increase, the valve snaps shut and stays closed until the end of the pump-up cycle. When the head is unloaded (a pressure switch unloader or similar device is still required), the CS valve re-opens, and is ready for the next start up.

Body and piston are brass, with a stainless steel spring and fluorocarbon o-ring.
