1 ONE-LOK Series SLC/SLCE Restraint for AWWA Use the SIGMA ONE-LOK Series SLC/SLCE restraint for AWWA pipe at mechanical or push-on joint ductile iron fittings. The ONE-LOK Restraint Systems can successfully be used for the restraint of Molecular Oriented PVC s manufactured in accordance with AWWA. Rated pressure of the restraint is limited to the rated pressure of the PVC pipe. Sample Specification for Restraint: Restraint for standard mechanical joint fittings shall be incorporated in the design of the follower gland and shall utilize multiple wedge segments that act against the pipe, increasing their resistance as the line pressure increases. The assembled joint shall maintain the maximum flexibility and deflection of all nominal pipe sizes after burial. Restraining gland, wedge segments, and actuating bolts shall be manufactured of high strength ductile iron conforming to the requirements of ASTM A536, Grade Dimensions shall be compatible with standardized mechanical joints conforming to the requirements AWWA C111/ANSI A21.11 and AWWA C153/ANSI through 24 (latest revision). Breakaway tops shall be incorporated in the design of the actuating bolts to visually ensure proper torque. The manufacturing of the actuating bolt must incorporate a quality control procedure that is deemed acceptable by the specifier and positively assures precise and consistent operating torque of the breakaway top. The mechanical joint restraining devices shall have a working pressure rating of 200psi minimum and provide no less than a safety factor of 2:1. Restraint shall be FM approved in applicable sizes. Restraining device shall be SIGMA ONE-LOK or approved equal. SIGMA Corporation 700 Goldman Drive Cream Ridge, NJ p f crm-sales@sigmaco.com SIGMA Corporation 1

Clean the fitting socket and pipe end. Lubricate gasket and pipe end with soapy water (or approved pipe lubricant meeting AWWA C111). Install ONE-LOK restrainer on the pipe with the lip extension facing the pipe end, followed by the proper mechanical joint gasket, tapered side toward pipe end. Insert pipe into the fitting outlet and seat the gasket firmly and evenly into the gasket cavity. Maintain a straight joint during assembly. 2. Push the ONE-LOK gland toward the fitting and center it around the pipe with the lip evenly pressed against the gasket. Insert the T-bolts and hand tighten in an alternating manner maintaining an even gap between the gland and the fitting face at all points around the socket. Continue tightening until all the T-bolts are within the suggested torque per AWWA C111, latest revision. Use of a torque wrench is recommended. Following proper assembly of the mechanical joint, hand tighten all actuating bolts until complete contact of the wedge segments is made with the pipe. Caution: Overtighting T-bolts may compromise integrity of joint. 3. Tighten each actuating bolt clockwise, ALTERNATING BETWEEN BOLTS (star pattern) until all the breakaway tops have been removed. Never tighten an actuating bolt more than 180 degrees before moving to the next bolt. If removal is necessary use the remaining 5/8 hex heads. In the absence of the breakaway tops, tighten all actuating bolts using the residual hex shank until the metal bolt collars bottom out in the gland housing. If the SLCE is removed from the pipe, be sure all of the bolts and wedge segments are in place before the SLCE restrainer is reassembled. 2 SIGMA Corporation

6 PV-LOK Series PVM/PWM Restraint for AWWA Installation Instructions for PV-LOK PVM/PWM on 1. Install plain-end PVC pipe into the mechanical joint bell. Insert one of the extra-long T-bolts provided with Series PWM through one of the bolt holes, marking a reference line on the pipe approximately 1 to 2 inches from the end of the bolt. 2. Assemble the MJ gland, gasket and bolts to AWWA standards. Assemble PWM clamping ring on the pipe at the reference line. Tighten the side clamping bolts to recommended torque. The protrusions on the restrainer ears must face the fitting to insure proper direction of the angled serrations. Line up the ears with the corresponding MJ bolt holes. 3. Insert the extra-long T-bolts and install one nut each between the gland and the clamping ring. Tighten the nuts against the MJ gland to AWWA standards to complete the gasketed assembly. Caution: Overtighting T-bolts may compromise integrity of joint. 4. Snug the retaining nuts behind the restrainer ears (against the flat surface). Do not over-tighten retaining nuts, approximately one turn with a wrench. Installation Instructions for PV-LOK PVP/PWP on 1. Assemble plain-end PVC pipe into bell according to pipe manufacturer s recommendations. 2. Assemble the Series PVP clamping rings on the spigot pipe (approx. 2 inches behind the insertion mark on the pipe) and immediately behind the pipe bell end, making sure the protrusions on the restrainer ears face toward each other to insure proper direction of the angled serrations. Tighten the side clamping bolts to recommended torque. 3. Insert the restrainer rods provided and snug the retaining nuts against the restrainer ears (against the flat surface). Do not over-tighten retaining nuts, approximately one turn with a wrench. Installation Instructions for PV-LOK PVPF on 1. Assemble plain-end PVC pipe and PVC pressure fitting according to pipe manufacturer s recommendations. 2. Install the non-serrated, two-piece interlocking ring set behind the gasketed bell of the PVC fitting. The bevel of this ring set should face the end of the fitting, allowing the retainer ring to seat evenly against the fitting bell. 3. Insert the restrainer rods through the retainer ear back toward the pipe and mark a reference line approximately two inches in from the rod end. Install the serrated clamping ring at this mark, making sure the protrusions on the restrainer ears face toward the fitting bell to insure proper direction of the angled serrations. Tighten the side clamping bolts to recommended torque. 4. Insert the restrainer rods provided and snug the retaining nuts behind the ears on both the clamping ring (against the flat surface) and back-up ring. Do not over-tighten retaining nuts, approximately one turn with a wrench. 6 SIGMA Corporation
