Page 35: Bv Breather Valve
12.2 BV Breather Valve 12.2.1 Use • On SAV control devices • On regulators (pilots) • On the SRV (SL10) 12.2.2 Application / Function The breather valve is used as replacement for the costly and time-consuming laying of breather lines and for securing the installation room against inadmissible escape of gas from diaphragm comparator compartments of gas pressure regulators and safety shut-off valves. -
Page 36: Rsd Restrictor Valve
12.3 RSD Restrictor Valve 12.3.1 Use • For installation in the measurement line of the gas pressure regulator 12.3.2 Application / Function • For finer adjustment of the control behavior of the regulator • For vibration-free outlet pressure regulation. The RSD is a throttle valve that affects the volumetric flow in the measurement line from outside by means of a continuously adjustable narrowing of the cross-section. The adjustment is done by means of an Allen key (4 mm). -
Page 37: Signal Transmitter/ Reed Contact
• On SAV control devices 12.4.2 Application / Function The signal transmitter, in conjunction with products from Medenus GmbH, is used for monitoring the position (position closed or open) of the safety shut-off valve via remote display. A built-in neodymium magnet in the pull knob of the SSV and a set switching distance to the reed contact cause a sensor to query the position of the safety shut-off valve and to transmit a signal via remote display. - Page 38 12.4.4 Mounting • Replace the pull knob of the SSV spindle with the pull knob with the neodymium magnet. • Mount the SSV cap included in the delivery, make sure that the SSV is open and slide the signal transmitter into the groove provided for this purpose at the SSV cap.
- Page 39 Safety instructions Must be read prior to using the neodymium magnet! Important safety instructions for general and responsible handling of the neodymium magnet Please pass on these instructions to all employees, customers and other people who are handling our products or parts derived from them.

Page 40: Inductive Signal Transmitter
• On SAV control devices 12.5.2 Application / Function The inductive transmitter, in conjunction with products from Medenus GmbH, is used for monitoring the position (position closed or open) of the safety shut-off valve via remote display. A sensor queries the position of the safety shut-off valve and a signal is transmitted via remote display. If the SSV drops into the closed position, the switching distance will be exceeded and the sensor will lose the signal. - Page 41 2/BU M12x1 12.5.5 Mounting • Unscrew the SSV cap of your Medenus gas pressure regulator (-) and replace it with the SSV cap with M12 threaded hole for the inductive transmitter and the pull knob, if necessary. (During mounting, make sure that the O-ring has been...

Page 42: Ssv Remote Release
12.6. SSV Remote Release 12.6.1 Use • On SAV control devices 12.6.2 Application / Function The direct-acting solenoid valve is used as electromagnetic remote release for closing the safety shut-off valve. Only for SSV control devices of functional class A. Upon being energized or in case of power failure, the valve closes the impulse line, resulting in the pressure falling below the response pressure to be monitored. - Page 43 approx. 101 12.6.4 Application example Breather line 3/2-way valve Breather line Impulse line © 05.2022...

Page 44: Ssv Remote Release
12.7 SSV Manual Release 12.7.1 Use • On SAV control devices 12.7.2 Application / Function By actuating the ball valve, the safety shut-off valve SSV is triggered and seals the gas flow gas-tight. The SSV manual release is only available for the SSV control devices of functional class A. After being released, the safety shut-off valve can only be opened by hand and engaged in the open position. -
