The regulator is available with the following options: Anti-tamper Oxygen Service For more information about hazards and risks of oxygen enriched systems see the Swagelok Oxygen System Safety technical report (MS-06-13). Cleaning and packaging to ensure compliance with product cleanliness requirements stated in ASTM G93 Level C is available.
Installation CAUTION Do not use the regulator as a shutoff device. A level of leakage across the regulator seat can occur during normal operation. Points of Attention Before Installation This regulator can be equipped with a variety of different options. Before installing the regulator you should fully understand the functions of the supplied options and the suitability of your particular regulator for the intended application.
Operation Required Tools for Operation A 19 mm open-ended wrench is required for changing the set pressure on a standard regulator. A 19 mm and a 32 mm open-ended wrench are required for anti-tamper regulators. Points of Attention Before Operation CAUTION The product can be hot or cold, depending on the environmental temperature and the process media temperature.
To reduce maintenance related system downtime to a minimum, either during commissioning or normal operation, Swagelok recommends having maintenance kits readily available on site. The need for maintenance kits is particularly important during the commissioning phase of a system installation due to residual assembly debris remaining in the system.
Points of Attention Before Removal from the System Swagelok recommends removing the regulator from the system for servicing and maintenance. Follow all local system safety and maintenance procedures when removing the regulator. WARNING Before removing a regulator from the system, to avoid personal injury, you must: •...
Maintenance kit components will be supplied preassembled where practicable to aid reassembly. Swagelok recommends replacing all O-rings removed during disassembly. Swagelok recommends that dynamic O-rings should be lightly lubricated per Table 2. NOTICE All threaded components must be lightly lubricated per Table 2 before reassembly to avoid...
Reassembly RS(H)10 Series: Standard Diaphragm Sensing 1. Fit the body plate (10) into the body (9) and retain with the retaining ring (11). 2. Fit the Seat O-ring (8) into the body (9) and ensure that it is seated all the way round. 3.
RS(H)10 Series: Standard Piston Sensing 1. Follow steps 2 through 9 of the RS(H)10 series standard diaphragm sensing reassembly procedure. 2. If present fit the body plate (10) into the body (9) oriented per Fig 3. 3. Fit the piston plate O-ring (20), piston O-ring (17) and, if present, piston backup ring (18) onto and into the piston plate (19).
Testing Swagelok recommends that the regulator be tested for seat and shell leakage to atmosphere. A well performing regulator will not show any indication of leaking. If any evidence of a leak is identified this must be rectified. Any damaged components must be replaced.
