Positive Choke, FC-140 Trim, 2 in × 602 F×M, 3/4 in Max Bean, 6,000 psi, Sour Service, No Cap

The Positive Choke, FC-140 Trim, 2 in × 602 F×M, 3/4 in Max Bean, 6,000 psi, Sour Service, No Cap is a positive choke valve rated for 6,000 psi working pressure (5K class), 2 in 602 Female Weco Union inlet × 2 in 602 Male Weco Union outlet, FC-140 trim. NACE MR0175 / ISO 15156 sour-service compliant. no cap.

Positive choke — fixed bean (orifice plate) controls flow rate / back-pressure at a calibrated opening. FC-140 trim with bean maximum 3/4 in max. Beans are interchangeable as a service item: replace the bean to change the orifice. Used where a stable, repeatable setting is required (e.g. extended well-test or production-allocated flow).

Construction

Performance

Working pressure 6,000 psi. Fixed-orifice flow control via interchangeable bean. Bean is hardened tungsten-carbide for sand erosion resistance. NACE MR0175 sour-service compliant — material class EE.

Applications

• 6K sour production allocation
• 602-iron flow-back chokes
• Sour well-test bench
• Production-test calibrated bypass

Compliance

• Manufactured to recognised oilfield flow-control design standards
• Material class EE (API 6A chemistry / sour-service grading)
• NACE MR0175 / ISO 15156 (sour-service)
• Mill test reports per EN 10204 3.1 / 3.2

How to order

Confirm (a) upstream and downstream pressure (the choke must handle the full ΔP across the trim), (b) inlet and outlet end-connection sizes / styles, (c) service class (standard vs sour), (d) trim model preference (FC-140 for 2-inch flow iron), (e) any auxiliary features (autoclave tap for pressure / sample, gear handwheel for high-torque). Indus quotes ex-works OEM for build-to-order, with full mill test reports and pre-shipment hydrotest certificates.

Companion products

Pair with matched-pressure block valves (ball, gate, plug) upstream and downstream of the choke. For frac iron, the 1502/602/206 Weco union family is the matched standard. For positive chokes, stock a range of bean sizes covering the full operating envelope (typically 1/4" through 3/4" or 2") so the operator can change settings without procurement lead.
