B1HTG Series:  High temperature flow control to 800°F (426°C)

BST's B1HTG series flow control chokes can handle high temperature, high pressure steam with ease, using the same body (and having the same dimensions) as the B1 series.  Precompressed Graffoil® seals require no adjustment once set.  The EZ-VU handle with locking screw is standard.

 

Features:

•  EZ-VU handle allows 64th indications to be viewed from any desired angle around the choke.  Handy T-Bar handle is optional.

•  Easily tuned for precise adjustment and control.

•  Can be locked in the adjusted position.

•  Precompressed Graffoil® static and dynamic seals.

•  All internal control surfaces constructed of 17-4 PH stainless steel.

•  Easily readjusted, even at high working pressure differentials.

•  Easy, safe access to internal parts without removing the body from the line.

•  Available in a wide variety of end connections (buttweld, socketweld, threaded NPT/LP, API 6B or ANSI B16.5 flanges) and sizes (1", 2", 3").

•  Standard trim sizes are ¼", ½", ¾", and 1", standard material is 17-4 PH stainless steel, heat treated to the H900 fully hardened condition.

•  Standard 4130 alloy steel body and bonnet rated to 3,000 psi working pressure at 60°F, derated as temperature exceeds 250°F to 800°F.

•  Angle body (shown above) or through body (see B1) are standard styles.

•  Corrosion resistant alloys optional.

•  Electric actuators available - contact BST Engineering.

•  Contact BST Engineering for standard centerline to flange face dimensions.

•  Designed and manufactured in compliance with API Spec 6A.
