Hub End Check Valve

Design to API 6D and Face to Face Distance as per manufacturers standards.
Hub Ends are available on Dual Plate Check Valve as well as Non Slam Axial Flow Check Valves.
Hub connections are used on Offshore and sub sea pipelines, where weight is a major design criteria.
Hub End Valves being lighter, saves weights saves money, as compared to ANSI Flanged End Valves.
Hub Clamp are generally selected by the customer being proprietary design of Techlok, Grayloc and Vector Hub Clamp, Flovel will design and end connection suitably.
Clamp connections uses 4 bolts hence quick connection and installation as compared to ANSI Flanged End valves.
Clamp connection ensures proper clamping force resulting in no leakage during bending and vibrations which generally occurs in long pipelines.
Seal Ring profile is precisely machined using CNC machines and special inserts.

Non Slam Check Valve

Non Slam Check Valve Short Travel and Ultra Light weight Disc make the functions of Non Slam Check Valves possible. Quick closing and fast traveling disc are the key design features. High Velocity and Gas Flow under Compressed conditions some times reach sonic velocity and the sonic booms are detrimental to the valves. The simple but precisely calculated spring design over comes such problem.

Non Slam Nozzle Check

Design to API 6D and Face to Face Distance as per manufacturers standards.
Fast acting spring prevents water hammer and pressure SURGE, this is a truly Non Slam Check Valves.
Short Travel and Ultra Light weight Disc make the functions of Non Slam Check Valves possible. Quick closing and fast traveling disc are the key design features.
High Velocity and Gas Flow under Compressed conditions some times reach sonic velocity and the sonic booms are detrimental to the valves. The simple but precisely calculated spring design over comes such problem.
Bernoullis equation of conservation of energy is the solution for spring design. Velocity head exchange the energy with Pressure Head and Non Slam Check keep on performing without the fear of sonic boom and valves offer least Pressure Drop when compared to Dual Plate Check Valves.
