The barrel of the valve has two sidearms attached at 180 to each other and on the same plane. The PTFE valve plug has three Viton O-rings. Two of the O-rings are on the shaft of the valve plug, making a dynamic seal between the plug and the barrel of the valve. The third O-ring is on the tip of the valve plug and makes the primary seal to the barrel valve seat. The caps on the valve stems are manufactured from Delrin. The valves feature a precision-formed tapered valve seat and a tooled external thread. The design of the cap and and the valve stem provide a non-rotating primary seal. The valve stems are completely interchangeable between valves of the same bore size.
