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 3. NOTICE All threaded components must be lightly lubricated per Table 3 before reassembly to avoid...
Reassembly BS(H)2 Series: Secure the body (1) in a vise, holding on the flats. Insert the seat retainer (2) into the body (1). Fit the body plug O-ring (5) onto the body plug (6). Insert the seat (4) and seat O-ring (3) into the body plug (6). Ensure the seat (4) is oriented correctly per Fig 3.
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.
Troubleshooting Symptom Cause Remedy Constant leakage from the outlet before the set pressure A damaged seat and/or poppet. Replace the seat and/or poppet. is reached. A damaged O-ring. Replace the O-ring. Leakage between the body Insufficient torque on the spring Tighten the spring housing/dome per and the spring housing/dome.
