Bolted couplings are for all lines carrying dry materials. These are an economical, reliable method of connecting conveying lines. It is constructed of galvanized steel or stainless steel. These are designed for use in pneumatic conveying & vacuum systems of dry materials operating at under 15 PSI.

Bolted flange joint assembly is widely used in chemical and nuclear plants. Generally, a bolt axial tension is applied by the torque control method for the bolted flange joint assembly.

Bolted joints are most common elements in construction and machine design. These consist of cap screws that capture and join other parts, and are secured with the mating of screw threads. There are two main types of bolted joint designs. In one method the bolt is tightened to a calculated torque producing a clamp load. The other type of bolted joint does not have a designed clamp load but relies on the shear strength of the bolt shaft.

Bolted Nozzle Ball Valves support bolts are furnished in stainless steel for external resistance to corrosion. Ball is diamond turned after molding to spherically perfect to assure precise sealing .The ptfe self-lubricating stem bushing prevent binding and provides low torque turning.  It provides premium corrosion resistance for most inorganic acids and caustics. Valves are available in standard and full port in most sizes.  Optional mounting brackets and locking handle.  Service kits are available. It unique self-aligning ball rotates freely against teflon ® seats. Its unique body-to-flange design allows low torque on and off operation. All valves are tested by air pressure under water
