Sleeve-Type Control Valves

Sleeve-type control valves throttle through a perforated sleeve that characterizes flow and contains cavitation and noise at the trim instead of in the piping, with the plug guiding inside the sleeve for stable control under varying loads. The range covers a WCB/SS304/SS316 body with SS304/SS316+PTFE cores and SS304/SS306/PTFE seats under PTFE packing, rated Kv from 6.9 to 690 (linear) and 6.3 to 630 (equal percentage), rated travels of 16/25/40/60 mm with diaphragm effective areas 280 to 1000 cm², nominal pressures PN1.6/4.0/6.4 MPa, an inherent adjustable ratio of 50, service bands of -20 to 200℃ standard or -40 to 450℃ with heat-dissipation bonnet, 20-240 KPa signal ranges, 0.14-0.4 MPa air supply, and full dimension and weight tables DN25-DN300. Selection turns on the differential pressure the sleeve trim must absorb with or without a positioner, the flow characteristic against the loop, and the bonnet band against line temperature.

Ordering & documentation

Documents

Ask for the documentation set with the inquiry — typical items (material certificates, test reports to the listed inspection standard, dimensional drawings) are confirmed and supplied with the quotation.

Quotation

Send the medium, temperature, pressure, size and connection for a quotation-ready inquiry. Lead time, MOQ and price are confirmed at quotation, together with the documents to be supplied with the order.

Sample & supply

Supply terms, order quantities and lead time are agreed per order — state the destination country and required schedule with the inquiry.

Storage & shipping

Store valves with seats and seals protected from UV, ozone and deformation, and keep end-face protectors on until installation; storage limits and shipping arrangements for the selected materials are confirmed at quotation.
