Pneumatic Angle Control Valve
The pneumatic angle control valve is the 90-degree, actuated execution of the angle control valve line: a WCB, WC6, CF8 or CF8M body turning the flow path through a right angle, with SS304/SS316/cobalt-chromium hardfacing alloy seat and plug sealing, SS304/SS316 cage and guide sleeve, and a steel or aluminium balanced piston with fluorine, reinforced PTFE or flexible graphite ring. The benchmark execution spans DN20 to DN400 at PN16 to PN100 and Class 150 to 600, with flanged RF/MF/RTJ ends and a 50:1 adjustable range.

Application & selection guidance
Select this execution where the pipework wants an angle body anyway - elbow positions, drain and flashing service where the right-angle path erosively attacks a straight globe - and pneumatic actuation drives the modulating duty. Pick the body casting against medium and temperature, choose metal sealing (IV grade) or soft sealing (VI grade) against the leakage requirement, and confirm the Cv range covers the loop.
Frequently asked questions
Where does an angle body earn its place on a control loop?
The right-angle flow path suits corner, drain and flashing duties where erosion would cut a straight globe seat, and it removes one elbow from the pipework. The benchmark page bodies the valve in WCB, WC6, CF8 or CF8M from DN20 to DN400 at PN16 to PN100 and Class 150 to 600.
What sealing and leakage classes are declared?
The benchmark page lists metal sealing at IV grade (0.01% of rated capacity) and soft sealing at VI grade (foam grade), with SS304/SS316/cobalt-chromium hardfacing alloy on seat and both plug sealing faces and SS304/SS316 cage and guide sleeve.
What is the controllable range and Cv coverage?
The benchmark page declares a 50:1 adjustable range (30:1 for Cv below 6.3) with percentage Cv 1.6 to 630 and linear Cv 1.8 to 690, and linear, percentage or quick-open flow characteristics.
Ordering & documentation
Documents
Ask for the documentation set you need with the inquiry β typical items for this execution (material certificates, test reports to the listed inspection standard, dimensional drawings) are confirmed and supplied with the quotation.
Quotation
A quotation-ready inquiry states: nominal size and pressure rating, body and seat material preference, end connection, operation, and the service medium with temperature. Typical values on this page are benchmark reference ranges; the binding values are confirmed at quotation.
Sample & supply
Supply terms, order quantities and lead time are agreed per order β state the destination country and required schedule with the inquiry.
Storage & shipping
Store valves with seats and seals protected from UV, ozone and deformation, keep end-face protectors on until installation, and for elastomer- or PTFE-seated executions avoid prolonged outdoor storage β seat compounds age fastest in direct sunlight and freezing conditions.
