The medium pressure regulator type 810 is a 1st stage pressure regulator which reduces the unregulated pressure from the liquid gas container to 1.5 bar outlet pressure.
A safety shut-off valve (OPSO 2.3 bar) and a safety relief valve (PRV 2.6 bar) are fitted to the pressure regulator as safety-related equipment.
The medium pressure regulator 811 is additionally equipped with an emergency supply connection.
The 2nd stage is usually carried out via a low-pressure regulator 320 upstream of the house inlet, which must be purchased separately.

OPERATING PRINCIPLES
The medium pressure regulator 810 / 811 reduces the unregulated pressure from the liquid gas container in a single stage to 1.5 bar.
In the event of an impermissibly high increase in the outlet pressure at the pressure regulator, 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. 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, after the set response pressure has been reached the
set response pressure, the safety relief valve (PRV) automatically releases a limited amount of the gas flow into the atmosphere.

TYP MDR-810 / 811 with OPSO and PRV
DESCRIPTION
The container pressure regulator type 810 is a pressure regulator of the 1st stage, which regulates the unregulated pressure from the liquefied gas container to a fixed pressure. The following safety equipment is fitted to the pressure regulator: a safety shut-off valve (OPSO) and a safety relief valve (PRV).
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 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. 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.
from a gas cylinder.
B. MODE OF OPERATION
The pressure regulator reduces the unregulated pressure from the liquid gas container in a single stage to a nominal 1.5 bar. In the event of an impermissibly high increase in the outlet pressure at the pressure regulator, 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. 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) will automatically release a limited amount of the gas flow into the atmosphere after the set response pressure has been reached.
C. ASSEMBLY
The pressure regulator is connected to the extraction valve of the LPG container with the POL connection according to DIN 4811, and is to 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 medium pressure regulator).
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
