Axelson ESPHL – High-Low Pressure Controller

ESPHL by AxelsonAxelson ESPHL

The ESPHL High-Low Pressure Controller is used with safety valve installations to provide automatic opening and closing control for safety valves at present pressure conditions.

The Axelson ESPHL Sensor Unit provides a means of mounting two sensors in series to perform a “High – Low” PSHL function.

The “ESP Sensors” in the unit will sense predetermined high and low pressure limits selected by requirements of the installation.  On sensing either of those limits, the unit is designed to close the surface safety valve.

Use the ESPHL to mount two “Sensors” in a series to perform a PSHL function.  The sensor may be mounted on any pressure containing device.

 

Axelson ESPHL Sensor

 

The ESPHL Sensor Unit provides a means of directing flowline pressure to sensing ports of two sensors.  The unit will block and bleed instrument pressure at a predetermined “High” or “Low” pressure setting to cause downstream safety components to react as programmed.

It also provides a single mounting point. A variety of ESP sensors may be mounted on the control block. Sensors adaptable are the diaphragm, high flow, or standard. The mounting base has a maximum working pressure of 10,000 psi and a test pressure of 15,000 psi. It is available in carbon steel and stainless steel and has 1/2-in. NPT female mounting connections.

Installation –

The ESPHL is designed to mount on a vessel or flowline in a vertical position; however, orientation is not critical. Connect the instrument supply to the inlet (Port B) of the low pressure sensor and outlet (Port C), of high pressure sensor to downstream safety components.

Natural Gas for Our Future
Natural Gas an ideal fuel source for many reasons, including safety. Natural Gas is lighter than air. This means that it will not puddle (like gasoline) or sink to the ground like propane, which is heavier than air. Instead, Natural Gas will rise and dissipate in the atmosphere. Natural gas also has a higher ignition temperature. This means that it is much harder to ignite. Also the storage systems used for compressed natural gas are infinitely stronger that the gasoline tanks found on cars and trucks today.
