Investment Castings for Needle Valves

Needle valve

Robust components for accurate metering

Needle valves are the primary solution when precision flow control takes precedence over regular on/off switching. A needle valve consists of a needle attached to a threaded stem that, when rotated, raises or lowers the needle to regulate flow with high precision. The tapered needle sits flush against the tapered seats, creating a secure seal and cutting off the flow when throttling isn't required.

Super Quali Cast is a leading producer of investment castings for needle valves, using the lost-wax technique to create the bonnet, body, and end pieces. Our automation-led process, SoftCast simulated prototyping, and in-house non-destructive testing (NDT) ensure we deliver repeatable quality. Our emphasis on quality, secure packaging, and technical support helps us supply to domestic and international OEMs and valve manufacturers. We export to all leading countries, including the U.S.A, the U.K, Saudi Arabia, and Australia.
