MDR 815

Container systems commercial & industrial

The medium pressure regulator 815 is a 1st stage pressure regulator for LPG, which reduces the unregulated pressure from the LPG container to 0.75 – 2.5 bar outlet pressure.

A safety shut-off valve (OPSO) and a safety relief valve (PRV) are fitted to the regulator as safety-related equipment.

OPERATING PRINCIPLES

The pressure regulator reduces the unregulated pressure from the liquid gas container in a single stage to 0.75-2.5 bar.
In the event of an impermissibly high increase in the outlet pressure at the pressure regulator, the response pressure of the overpressure 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 pressure relief valve (PRV) automatically releases a limited amount of the gas flow into the atmosphere after the set response pressure has been reached.

INSTALLATION AND OPERATING INSTRUCTIONS

PN 25 medium pressure regulator – “f” – 40-60 kg/h
DVGW approved: According to EN 16129/ CE approved according to 2016/426/EG

TYPE MDR-815 with OPSO and PRV

DESCRIPTION
The pressure regulator type 815 is a 1st stage pressure regulator that reduces the unregulated pressure from the LPG container to a set outlet pressure. A safety shut-off valve (OPSO) and a safety relief valve (PRV) are fitted to the 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 (see table) is reached. It must be opened manually after closing.

2. Pressure regulator MDR-815
The pressure regulator reduces the unregulated pressure from the liquid gas container to a set outlet pressure. (see table)

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 (see table). It closes again automatically when the pressure drops below the set pressure.

4. Emergency supply connection
If necessary, the emergency supply connection can be used to provide an emergency supply from a gas cylinder by means of a connection hose. 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 0.75-2.5 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.

 

ATTENTION ! All activities described in points C, D and E may only be carried out by authorised specialist personnel.

 

C. ASSEMBLY
The pressure regulator is connected with a POL flange to the tapping valve of the LPG container, to be supported on the container by means of the support device supplied, or installed in a pipeline with a threaded flange. It is essential to ensure that the pressure regulator is installed with the ventilation openings facing downwards. (See note on the medium pressure regulator).

 

IMPORTANT ! – Only use proper tools for installation. – Avoid any force on the pressure regulator when tightening the POL connection. – Prevent sealants from getting into the gas-carrying components. – Always counteract threaded connections with suitable spanners. – After assembly, a careful leak test must be carried out.

 

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 no. 8
– Check the outlet pressure: test port G1/8 no. 3
– Set pressure and function test of OPSO/PRV: test port G1/8 no. 3

 

During the test, the gas supply must be interrupted and the consumer unit closed. A safe and quick function test can be carried out with the “Müller test device”. A leak test must be carried out after each test.
