ACT manufactures both Positive and Adjustable Choke Valve in pressure rating up to 15,000 PSI WP., with different styles of end connection.
Adjustable Chokes Valve are meant for variable flow. They have externally controlled indicator showing orifice size in the increment of 1/64th inch.The variation in choke valve size is achieved by rotating hand wheel to obtain desired flow rate at down stream side.
ACT Adjustable Choke Valve contain the following features:
Interchangeability of parts to construct a positive, adjustable, or combination choke
Bonnet nut has rugged, integrally forged lugs for hammering nut loose
Built-in safety feature which releases residual pressure in the choke valve body before the nut is fully removed. The inside of the choke body is vented to atmosphere after the bonnet nut is partially removed
Interchangeability of component parts for a particular pressure range. For example, the same blanking plugs and bonnet assemblies are used in nominal 2” 2000 through 10,000 PSI WP.
Stainless steel adjustable choke valve needle and seat (Tungsten Carbide/ Ceramic lining needle and seat also available for severe service applications)
Different end connections (API / ANSI, Flanged / Threaded) choke valve are available upon request.
