Synthetic rubber <br />shall be molded in place and bonded to the wedge; mechanical fasteners are not allowed. <br />Stem shall be sealed by at least two O-rings; contained within the stuffing box (grooving of <br />stem O-rings is not allowed). All stem seals shall be replaceable with the valve wide open <br />and while subjected to full rated pressure. Valve body and bonnet shall be coated, inside <br />and out; with fusion-bonded epoxy. Bonnet and stuffing box bolts and nuts shall be type <br />18-8 stainless steel and must be installed by the manufacturer. <br />(vi) Gate valves shall be manufactured by Mueller, Clow or American Flow Control. <br />(vii) Gate valves shall be configured for installation within 3 feet of adjoining fittings.
