Internal parts of the valve comprises a valve

A flow channel connected to the valve housing. Under normal circumstances, including to prevent leakage around the stem, and provides a program on the actuator assembly Rev. divided body. : Valve pressure chamber. It also provides a connection end of the tube and the fluid flow passage, and the support surface of said valve seat and the valve closing body. The most commonly used in the valve structure: a) a valve seat of the valve port having a valve seat and valve body, b) the double-seat valve, a valve seat of the two valve ports, and a coil, Ç) having an inlet and three fluid ports fluidly connected a bidirectional valve body outlet ð) side of the body, wherein the two connecting terminals of the input and output common terminology (used for mixing liquids), or a compound-side input terminal and two outlet (dispersion liquid) of the valve cover and valve body valve body trim. More specifically, a part of the group, mention should be made of the valve assembly closed.
Body assembly (usually referred to as physical or valve, more accurately known as the body arrangements), Body, bonnet components, and the lower flange (if used) and decorative mounting. Trim enclosure assembly, open, closed or partially blocking one or more of the seat mouth.pneumatic auto drain
Spool: regular and spool exchange items, close the element.
Stem: straight traveling valve, the actuator rod of the connecting member and the closure member.
Booth: the implementation of the power of the unit is fixed to the valve structure.two position three way valve
Lever: connect the valve shaft rotation arm. Drive rod linear motion into rotary motion to find the rotary valve disc or ball. The rod is usually a small gap spline or other means to reduce the gaps and gap rotatable stem.
Global: rotary control valve fluid control components. It uses the Global passed through the fluid channel. The fluid passage and the diameter of the pipe is equal to or coincident.
Global: the rotary control valve, the fluid part of the control element. It uses the part of the ball, and through a.
V-ball: ball valve type is the most common part. V-notch ball, the ball part of the surface is polished or coated in a nearby seat rotates within the perimeter of the entire trip. V-shaped incision on the ball, you can achieve very high within the control of an equal percentage flow characteristic.
