Isolation and check valves, air-release valves, couplings, adaptors and repair clamps for water and wastewater pipework. Match materials and seals to the water quality and connections to the actual pipe dimensions.
Drinking water, process water and wastewater duties are treated as different material environments.
Air valves are selected for filling, normal operation, draining and vacuum-protection conditions.
Coatings, elastomers and metallic materials are selected around the water and installation environment.
Pipe material, outside diameter, flange drilling and restraint requirements are confirmed before selection.
Consider pump starts and stops, rapid valve closure and column separation in addition to normal pressure so components are not selected only for steady-state conditions.
Define whether equipment is buried, installed in a flooded chamber or above ground. Access, stem extensions and serviceability can change the required configuration.
For couplings, adaptors and restrained joints, confirm axial forces, anchor locations and allowable pipe movement before choosing the connection arrangement.
Filter by valve type, material or connection.
Provide the medium, pressure, pipe material and dimensions. Include the flange standard or outside-diameter range, installation conditions and required product documentation.
