KIMRAY 212 SGT BP Gas Regulator

KIMRAY 212 SGT BP Gas Regulator

The KIMRAY 212 SGT BP Gas Regulator is a highly constructed, pilot driven, integrated back pressure regulator designed to maintain a consistent upstream pressure in challenging marine automation, offshore production and industrial gas processing applications. The 212 SGT (Soft Gear and Teflon/Elastomeric sealing elements) incorporates an integral upstream pressure monitoring device that dynamically responds to line changes to prevent over-pressurization of important upstream assets.

This unit is designed for sour gas systems with a 2 inch connection size and the pilot controller and primary valve body are housed in a compact cast-ductile iron or steel enclosure. This configuration minimizes potential leak routes, resulting in zero-ambient emissions during non-actuation holding cycles and is suitable for use in an enclosed vessel engine room, inert gas systems (IGS) and offshore separator skids.

Model Details

• Brand: KIMRAY

• Specific Model Configuration: 212 SGT BP
• Manufacturer Part Number (MPN): 212-SGT-BP-AUTO / 212SGTBP

Specifications: KIMRAY 212 SGT BP

Key Features

1. Integrated Pilot Architecture: The detecting pilot mechanism and primary valve actuator are integrated into one structural casting, dramatically lowering the number of external tubing runs, eliminating misalignment and minimizing fugitive emission leak pathways.
2. High Sensitivity Regulation: The sensing diaphragm is large relative to the valve port, resulting in a very narrow deadband and rapid reaction to small changes in upstream pressure.
3. Sour Gas Optimization: Fully built with internal metallurgy and elastomeric choices to NACE MR0175 criteria for superior sulfide stress cracking resistance
4. Bubble-Tight Bubble Sealing: Utilizes the innovative SGT soft-seat trim design for positive, class VI shut-off, even when processing particulate-laden or low-molecular-weight gases.
5. Inline Field Serviceability: The top-entry design permits full inspection, trim replacement and diaphragm service without separating the main valve body from the industrial or marine piping manifold.

Applications

• Maritime Boiler Fuel Gas Supply: Regulates the upstream supply pressure of natural gas or vaporized LNG lines providing maritime propulsion boilers and auxiliary equipment.
• Offshore Production Separators Controls back pressure on low and high pressure oil/gas separators to maintain optimum thermodynamic equilibrium for phase separation.
• Inert Gas Systems (IGS): Controls the blanket pressure of inert cleaning gases on oil tankers and gas carriers during cargo discharge cycles.
• Wellhead Test Manifolds: Provides a constant pressure upstream of test chokes and metering devices during multiphase flow monitoring.
• Compressor Station Skids: Used as a bypass relief or suction-pressure regulating valve on multi-stage maritime and industrial reciprocating compressors.

Equipment Compatibility

The KIMRAY 212 SGT BP interfaces seamlessly with standard automation layouts and replaces older modular setups:

• Compatible Equipment: Fisher 627 series, WellMark 7400 actuators, Emerson/Tartarini regulators, and industrial SCADA pressure transmitters.

Tip for Commissioning

During startup, always back off the adjusting screw completely (counter-clockwise) before introducing line pressure. Slowly tighten the adjustment screw clockwise until the desired setpoint is reached. If you observe rapid valve cycling or chattering under low-flow conditions, consider down-sizing the internal trim package rather than adjusting the spring; running the regulator below 10% of its rated Cv causes velocity erosion on the soft SGT seat matrix.
