Panel-Mount Threaded On/Off Valves
Access the handle of these valves while protecting your line behind an instrument panel. They have threads and a hex nut below the handle for panel mounting.
316 stainless steel valves are more corrosion resistant than brass valves.
Valves with an anchored ball are best for high-pressure applications where flow would push the ball in a standard ball valve. The ball in these valves is secured at both ends to create a tight seal and reduce the effort needed to open and close these valves.
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.

High-Pressure Threaded On/Off Valves
Rated for at least three times the pressure of standard threaded valves, these valves are used to start and stop the flow of compressed gas, pressurized water, or steam.
316 stainless steel valves are more corrosion resistant than steel valves.
Standard-port valves slightly restrict flow.
Valves with an anchored ball can be used with higher pressures than standard ball valves. Their ball is secured to the top and bottom of the valve body, which keeps it from shifting with the flow of liquid. This creates a tight seal—even when the ball is rotating—and reduces the force needed to open or close the valve.
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.
