Current through Register Vol. 46, No. 28, July 10, 2024
(a) Each service line must have a service
					 line valve that meets the applicable requirements of this Part. A valve
					 incorporated in a meter bar that allows the meter to be bypassed may not be
					 used as a service line valve. All such exposed valves must be of tamper proof
					 construction.
(b) A soft seat
					 service line valve may not be used if its ability to control the flow of gas
					 could be adversely affected by exposure to anticipated heat.
(c) Each service line valve on a high
					 pressure service line, installed aboveground or in an area where the blowing of
					 gas would be hazardous, must be designed and constructed to minimize the
					 possibility of the removal of the core of the valve with other than specialized
					 tools.
(d) On service lines
					 designed to operate at pressures in excess of 60 psig (414 kPa), the service
					 line valve shall be the equivalent of a pressure lubricated valve or a needle
					 type valve. Other types of valves may be used where tests by the manufacturer
					 or by the user indicate that they are suitable for this kind of
					 service.
