YDTech™ OEM of custom "V" variants full port segmented control valve! supplier of precision custom V notch balls for control valve balls or hollow balls in china.

v-ball 2-way control valve accurately controls the flow of liquids or thick media in industrial and sanitary throttling, keeping media flowing smoothly and giving accurate control through the entire valve stroke with openings designed specifically for your process.

this economical, lowcost valve design translates into efficient, straight through flow, with a live-loaded rotary shaft sealing and tight shutoff in both directions. the flow characteristic is precision machined to a “v” shape to meet any control requirement. the controlling element is a 316l stainless steel ball with a choice of resilient seat options, but is also available in hastelloy, titanium, inconel, and bronze.

the v-ball is the ideal control valve for PH control when using a low flow opening and solid removal hole. the special opening of the ph control seats provides the most ideal throttling characteristics while allowing solids to move through the ball valve’s larger opening. temperature product mixing control.

tions that required tight shutoff. our v-ball valves solve these problems with tight shut off live loaded stem seals and tailored ball characteristics providing ramp up condition quickly while maintaining precision low flow control.

v-balls are for temperature and product mixing control because of their quick responses to process controllers’ signals and the precision to which they can control flow. their accuracy at low and high flow demands enhance their effectiveness.

v-balls have equal percentage flow characteristics, while the slotted balls have linear flow characteristics. as the ball rotates, desired flow rates can be achieved by positioning the ball anywhere between 0° and 90°. this provides high flow capacity and outstanding repeatability in manufacturing processes. custom openings are available to meet your unique control needs and provides an economical solution to more expensive rising stem control valves.

these valves also feature characterized balls with various port shapes, including v or slotted either manual or automated. v-ball is available in any 2-way series valve and can combine with features such as purge ports, crown flats and polishing.

controlling steam pressure is not easy. typical problems associated with globe control valves in steam service have been stem leakage, sticking, poor shutoff and high maintenance. linear stem valves require frequent packing adjustment and tightened packing sometimes means overshoot, oscillation and deviation from the setpoint. further, class iv shutoff is usually too much leakage for many applical.
