PART 3 - EXECUTION
GENERAL
Properly align piping before installation of valves. Install and test valves in strict accordance with valve manufacturer's installation recommendations. Do not support weight of piping system on valve ends.
Mount valves in locations which allow access for operation, servicing and replacement.
Provide valve handle extensions for all valves installed in insulated piping.
Install all valves with the stem in the upright or horizontal position. If possible, install butterfly valves with the stem in the horizontal position. Valves installed with the stems down will not be accepted.
Prior to flushing of piping systems, place all valves in the full-open position.
SHUT-OFF VALVES
Install shut-off valves at each piece of equipment, at each branch take-off from mains for isolation or repair and elsewhere as indicated.
BALANCING VALVES
Install where indicated on the drawings and details for balancing of flow in pumped hot water recirculation piping systems.
Upon project completion, adjust each valve and set position stop. Balance system to minimum flow in return piping branches needed to maintain even supply water temperature throughout building.
DRAIN VALVES
Provide drain valves for complete drainage of all systems. Locations of drain valves include low points of piping systems, downstream of riser isolation valves, equipment locations specified or detailed, other locations required for drainage of systems and elsewhere as indicated.
SPRING LOADED CHECK VALVES
Install a spring loaded check valve in each circulating pump discharge line, each clearwater sump pump discharge line and elsewhere as indicated.
SWING CHECK VALVES
Install swing check valves in recirculation branch lines and elsewhere as indicated. Provide weighted swing check valves at sanitary sump pump discharges.
PRESSURE REDUCING VALVES
Provide ball valve and strainer at inlet and ball valve at outlet. Install pressure gauges to indicate inlet and outlet pressure at each pressure reducing valve.
SAFETY RELIEF VALVES
Install relief valves on all pressure vessels and elsewhere as indicated. Inlet and outlet piping connecting to valves must be the same size as valve connections or larger. Pipe discharge to drain where indicated or to floor.
GAS PRESSURE REGULATORS
When the gas pressure regulator is equipped with a vent connection, run a connection size vent to outside air in accordance with codes. Use a larger size vent when required by the manufacturer's installation instructions.
COMPRESSED AIR VALVES
Install shut-off valves at each piece of equipment, base of drip legs and elsewhere as indicated. Install safety exhaust shut-off valves at terminal equipment designed for frequent removal. Install pressure reducing valves at filter stations and elsewhere as indicated. Mount in readily accessible location for gauge and maintenance access.
SEWER AIR AND VACUUM VALVES
Install sewer air and vacuum valves at high points of forcemains, at grade changes, every 1/2 mile on lines with little gradient and elsewhere as indicated. Locate in valve manhole with watertight cover, sealed to top of main and of sufficient depth to prevent freezing. Mount valves allowing access in manhole for backflushing and servicing.
