REDUCING VALVE SPECIFICATION
S 400, S 1500, S 2500, JETCONTROL 600 are a single stage regulators
suitable for pressure reduction of technical gases at high operating
pressure up to 200 bar, resp. 300 bar. They are provided with inlet and
outlet manometer, adjusting control knob (for adjusting required operating
pressure), inlet and outlet connection and types S 400, S 1500 by safety
valve. The inlet connection complies with national regulators of the
country where the regulators valves is used.
All pressure regulators are designed for 200 bar, resp. 300 inlet pressure
and every regulator is carefully assembled and tested by skilled personnel.
PROCEDURE
Installation and operation
1 .
Ensure that the appropriate regulator is selected for the type of gas and
maximum outlet pressure of the cylinder to be used.
DO NOT USE A REGULATOR IN A GAS SERVICE FOR WHICH IT IS
NOT DESIGNED.
2.
Gas cylinder must be in an upright position and secured.
3.
Check that the cylinder is clean and free from oil or grease. Open the
cylinder valve briefly to clean out any residual dirt or obstruction. Stand
clear of the outlet and wear eye protection for this operation.
4.
Check cylinder valve threads and if there is any evidence of damage -
do not use - return the damaged cylinder to the supplier.
5.
Inspect the regulator to ensure that it i s clean and free of damage.
6.
Connect the regulator to the cylinder and tighten in accessories with
type of the connection by hand or by spanner nuts for hand tighten is
necessary tighten only by hand (the use of a spanner will over tighten
and damage the threads).
7.
Connect downstream equipment to regulator outlet in readiness for op-
eration to be undertaken.
8.
Unscrew regulator pressure adjusting control knob i. e. to zero pressure
(turn anticlockwise).
9.
Open cylinder valve slowly to avoid a pressure gauge which could dam-
age the regulator.
10.
Open downstream valves to flow position and adjust regulator to re
-
quired pressure by the pressure adjusting control knob.
11.
The regulator is now ready to supply gas to the downstream equip-
ment.
Closing down procedure
1.
Follow recommendations from the manufacturer of downstream equip-
