The container pressure regulator reduces the unregulated pressure from the liquid gas container in two stages to a nominal 50 mbar.
In the event of an impermissibly high increase in the outlet pressure at the pressure regulator of the 2nd stage, the response pressure of the safety shut-off valve (OPSO) is reached, which then closes automatically and shuts off the gas flow upstream of the pressure regulator of the 1st stage. The respective operating status of the OPSO can be seen on the visual display.

Clear = open
Red = closed

If there is a further increase in pressure, e.g. due to the OPSO not closing completely, the safety relief valve (PRV) automatically releases a limited amount of the gas flow into the atmosphere after the set response pressure has been reached.

TYP BRK 110 / 111 with OPSO and PRV

DESCRIPTION
The container pressure regulator type 110 consists of a 1st stage regulator and a 2nd stage regulator which reduces the unregulated pressure from the LPG container to a fixed outlet pressure. A safety shut-off valve (OPSO) is fitted in the 1st stage pressure regulator and a safety relief valve (PRV) in the 2nd stage pressure regulator as safety-related equipment..

A. INDIVIDUAL DESCRIPTIONS
1. safety shut-off valve (OPSO)
The OPSO is open during normal operation and has the function of automatically shutting off the gas flow as soon as the set response pressure is reached. It must be opened manually after closing.

2. 1st stage pressure regulator
The 1st stage pressure regulator reduces the unregulated pressure from the LPG container to a set outlet pressure.

3. safety relief valve (PRV)
The PRV is closed during normal operation and has the task of automatically releasing the gas flow as soon as the pressure in the system to be protected has reached the set pressure.
It closes again automatically when the pressure drops below the set pressure.

4. 2nd stage pressure regulator
The 2nd stage pressure regulator reduces the output pressure of the 1st stage pressure regulator to a fixed output pressure of 50 mbar.
of 50 mbar.

5. emergency supply connection
The emergency supply connection can be used to provide an emergency supply from a gas cylinder by means of a connection hose, if necessary.

B. MODE OF OPERATION
The container pressure regulator reduces the unregulated pressure from the liquid gas container in two stages to a nominal 50 mbar.
In the event of an impermissibly high increase in the outlet pressure at the pressure regulator of the 2nd stage, the response pressure of the safety shut-off valve (OPSO) is reached, which then closes automatically and shuts off the gas flow upstream of the pressure regulator of the 1st stage. The respective operating status of the OPSO can be seen on the visual display.

Clear = open
Red = closed

If there is a further increase in pressure, e.g. due to the OPSO not closing completely, the safety relief valve (PRV) automatically releases a limited amount of the gas flow to the atmosphere after the set response pressure has been reached.

C. ASSEMBLY
The container pressure regulator is connected to the extraction valve of the liquid gas container with the POL connection according to DIN 4811. It must be supported on the container by means of the support device supplied.
It is essential to ensure that the pressure regulator is installed with an inclination of approx. 20° so that the ventilation openings point downwards (see note on the container regulator combination).

D. START-UP

Start-up is carried out by slowly opening the extraction valve on the liquid gas container.
If the OPSO has locked, the following steps are required:

• Close the extraction valve on the liquid gas container
• Relieve the pressure at the pressure regulator (inlet and outlet).
• Twist off the plastic cap of the OPSO
• Pull out the OPSO plunger until it engages.
• Screw the plastic cap back on
• Slowly open the extraction valve on the liquid gas container

E. functional test of the container pressure regulator

• Check the inlet pressure: test port G1/4
• Check the outlet pressure: test port G1/8
• Set pressure and function test of SAV/PRV: test port G1/8
