White Paper: Breakthrough Solenoid Valve Technology for Upstream Oil and Gas Heating Equipment

Low-temperature stainless steel fuel shutoff valves are usually utilized for on/off control of fuel gas
within gas fuel trains in process heating system burners. These systems are widely used by oil and gas firms as well by as original equipment manufacturers (OEMs) that produce gas heating equipment or burner management systems (BMSs) and controls in upstream oil and gas pipelines and tanks.

In recent years, a new generation of solenoid valve technology has been changing the shutoff valve game. Their modern designs provide pipeline and tank heating systems with robust, durable performance; safety; and regulatory compliance — all while increasing efficiency and productivity.

Many operators in North America and beyond are moving away from using pneumatically operated shutoff valves on their pipelines and tank heaters. They’re replacing them instead with valves introduced within the last decade by a few manufacturers — all based on solenoid shutoff valve technologies. White paper courtesy of ASCO.

Reversing the Failure Mode of a SAMSON 3271/3277 Actuator from Fail Open to Fail Close


INSTRUCTIONS

WARNING: Actuators with preloaded springs are under tension. They can be identified by three long bolts protruding from the bottom of the actuator. These should be removed last, and installed first upon re-assembly.
  1. With the actuator removed from the valve, unscrew the nuts and bolts on the diaphragm case.
  2. Lift off the top diaphragm case.
  3. Remove the diaphragm plate assembly consisting of the diaphragm plate, diaphragm, and actuator stem from the actuator case.
  4. Remove the springs.
  5. Clamp the bottom section of the actuator stem into a vise using protective jaws, ensuring the actuator stem is not damaged.
  6. Remove the collar nut.
  7. Remove the diaphragm plate from the actuator stem, flip upside-down and place them back onto the actuator stem.
  8. Re-install the collar nut.
  9. If necessary, apply a suitable lubricant to the actuator stem.
  10. Install the diaphragm plate assembly together with the actuator stem pointing downward into the bottom diaphragm case.
  11. Place the springs onto the diaphragm plate, centering them in the intended recesses. The final actuator spring range will determine the appropriate springs to be installed.
  12. Place the top of the actuator case onto the assembly. Ensure that the air connections on the cases are correctly aligned with each other.
  13. Fasten the top and bottom diaphragm cases together using the nuts and bolts. Observe tightening torques.
ABOUT THE SAMSON 3271/3277

The Type 3271 pneumatic rolling diaphragm actuator is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from the micro-flow valves to large 20"+ globe control valves.

The Type 3277 pneumatic rolling diaphragm actuator with an integrated accessory attachment area is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from the micro-flow valves to 4" globe control valves.

The thrust force of the actuator depends on the actuator area, pneumatic supply pressure, spring stiffness, distance traveled, initial compression of the spring, the number of springs internal to the actuator, etc.

The Type 3271 and Type 3277 Pneumatic Actuators contain a rolling diaphragm and internal springs and have the following special features:
  • Low overall height
  • Powerful thrust at high stroking speed
  • Low friction
  • Various bench ranges by varying the number of springs or
  • their compression
  • No special tools required to change the bench range or to
  • reverse the direction of action (also version with handwheel)
  • Permissible operating temperatures from –60 to +120 °C

Clamp-on Ultrasonic Flow Meters for HVAC and District Energy: How They Measure Up

Clamp-on Ultrasonic Flow Meter
While other flow measurement technologies (e.g. magnetic or vortex flow meters) are also used in district energy applications, clamp-on ultrasonic flow meters are often an optimal solution since they are externally mounted.They are especially well-suited for use with existing hot or chilled water distribution lines. In existing applications they are quick, easy and less expensive to install than other flow meter options because there is no need to cut the line, interrupt service, or drain the pipe. They also do not require the installation of bypass piping and valves for removal; maintenance expense is minimized since they do not have moving parts; and, used outside the pipe, they do not require periodic cleaning.

Clamp-on ultrasonic meters are also very versatile: They can be installed on the full range of district energy line sizes (and more - from 0.5” up to 394”), employed anywhere in the
hot or chilled water distribution process and used to measure two applications simultaneously. They may be installed where an “intrusive” flow meter is not possible or appropriate – when only temporary measurements are needed, for example. All measurements can be logged and time-stamped for creating analyses and reports.
