YDTech™ OEM of stainless steel stem steel(304L, 316L) trunion ball valves for control valve balls! supplier of precision float ball ceramics or titanium(Gr3, Gr4, Gr7) or hollow balls in china.

ball valves in sizes up to 2 inch generally

come in single piece, two or three piece

designs. one piece ball valves are almost

always reduced bore, are relatively

inexpensive and generally are throw-away.

two piece ball valves are generally slightly reduced bore, they can be

either throw-away or repairable. the 3 piece design allows for the center part of the valve

containing the ball, stem seats to be easily removed from the pipeline. this facilitates efficient

cleaning of deposited sediments, replacement of seats and gland packings, polishing out of

small scratches on the ball, all this without removing the pipes from the valve body. the

design concept of a three piece valve is for it to be repairable.

ball valves are durable, performing well after

many cycles, and reliable, closing securely

even after long periods of disuse. these

qualities make them an excellent choice for

shutoff applications, where they are often

preferred to gates and globe valves, but they lack their fine control in

throttling applications.

style ball prevents ball blowout and contributes to low operating torque. it is suitable for large

and high pressure ball valves. this design of trunnion valve ball provides automatic relief of

cavity overpressure. these balls are available with soft as well as metal seats designed for

either high temperature or cryogenic service.

in floating ball design, two seat rings are used to support the ball in a floating-ball design.the

flow control valve stem is attached to the ball at a slotted right angle to the ball valve's port.

this design makes the ball to float or move in the direction of the seat ring on top, when the

shaft is rotated. when the ball valve is closed, fluid pressure makes the ball to push against

the seat ring at the bottom. this design is suited for all differential ball valve body styles.

we specialize in manufacturing titanium valve balls, valve seats and spherical grinding

services. we have the technology, skilled craftsmanship and experience to manufacture a

wide variety of custom valve balls. if you have special requirements please contact us so we

can give your specifications the best and quickest analysis.
