3 in × 602 F×M adjustable manual choke, H2 trim, 3 in nom / 2 in max bean, 6,000 psi sour. Mid-pressure 3-inch sour-gas choke.
The Adjustable Manual Choke, H2 Trim, 3 in × 602 F×M, 3 in Nom / 2 in Max Bean, 6,000 psi, Sour Service is a adjustable manual choke valve rated for 6,000 psi working pressure (5K class), 3 in 602 Female Weco Union inlet × 3 in 602 Male Weco Union outlet, H2 trim. NACE MR0175 / ISO 15156 sour-service compliant.
Adjustable manual choke — handwheel rotates a threaded stem to vary the trim opening, controlling flow rate / back-pressure on the wellhead or test train. The H2 trim is replaceable as a service item — stem and seat can be removed without taking the body out of line. Bean / orifice maximum: 3 in nominal / 2 in max.
Working pressure 6,000 psi. Variable-orifice flow control by handwheel — full closed to 3 in nominal / 2 in max fully open. Position indicator on the bonnet shows current opening. Tungsten-carbide trim resists erosion in sand-laden flow. NACE MR0175 sour-service compliant — material class EE.
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 (N-60 for compact / lower-flow service, H2 for high-flow / 3-inch lines), (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.
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 data-rich operations, also specify autoclave taps with matching pressure transmitters and / or sample bombs.
