ZB ZK NB NK Axial Check Valve Specifications Z Type Size range: 1-10 (DN 25 - DN 250) Pressure Class: ASME 150 - ANSI 2500, API 2000 - API 20000 Non-slam closure Choice of face-to-face length Metal sealing Low pressure loss Low weight Maintenance free The axial design allows for a streamlined flow path around the disc and high pressure recovery, minimising pressure drop across the valve. This efficient design combined with the highly responsive non-slam operation make this valve ideal for high pressure, critical pump and compressor applications ZB - The ZB is the standard valve for sizes 1 to 10. With its optimum designed aerodynamic flow path through the valve the ZB produces very low pressure losses. It is also available with API6D face to face dimensions (ZD) ZK - With a shorter face-to-face than the ZB and where pressure loss across the valve is not such a significant consideration, the ZK is installed where space and weight is at a premium. The Z range is suitable for all kind of liquid and gaseous fluids and all installation positions. N Type Size range: 12-88 (DN 300 - DN 2200) Pressure Class: ASME 150 - ASME 2500, API 2000 - API 10000 Non-slam closure Friction-free valve disc guiding Maintenance free Low weight Very low pressure loss Metal sealing Choice of face-to-face length The unique ring disc design ensures that the disc remains light and responsive even in large sizes, which are essential for rapid non-slam closure. Mounted on a multiple spring and radial guide assembly, the disc moves freely without any of the frictional forces associated with the solid disc and shaft design. Combining two ring-shaped annular flow paths with the excellent pressure recovery properties provided by the diffuser, the minimal pressure drop across the N type valves gives lifetime energy savings when compared to more conventional check valve designs. NB - The NB is the standard long face to face valve for 12 and larger. It is also available with API6D face to face dimensions (ND) NK - Providing a shorter face-to-face length and reduced weight, the NK is the standard lower cost solution where marginally higher pressure drops can be accepted. The N range is suitable for all kind of liquid and gaseous fluids and all installation positions. Flanges Welding Ends Wafer Fully Lugged Wafer Hub Ends
Facilities and Resources s Check Valve manufacturing facilities in Stoke-on-Trent, England, comprises of a Steel and Super Nickel alloy foundry ( Steel Castings) and a well equipped CNC machine shop with full design, fabrication, inspection and test facilities ( International). The ISO 9001 foundry specialises in producing high integrity, pressure vessel castings from a few kilos to 18,000 kg in weight. The materials cast by the foundry include, ductile and Ni-Resist irons, carbon and low alloy steels, stainless steels, duplex stainless steels and super nickel alloys such as Hastelloy and Alloy 625. s ability to produce the special alloys is enhanced by our in-house 10 tonne AOD refining furnace. The design, machine and assembly shops cover some 14,100 m 2 and are equipped with 36 modern CNC machine tools that are the core of the production and are supplemented by many conventional machine tools. The test facilities include six hydraulic hydrostatic test rigs, the largest of which has a 2500 tonne hydraulic ram, and two pneumatic test rigs. Cryogenic testing is also carried out on site where valves are cooled by liquid nitrogen at -196 C and leak tested with helium gas. Valve design is carried out using 3D CAD and is verified on computers utilising finite element analysis and Flow Simulation programs. Both the foundry and the design, machining, assembly and test facilities are audited and accredited to ISO 9001:2008. Extensive in-house testing and laboratory facilities are available including:- Hydrostatic Pressure Testing (25000psig/1725barg) High Pressure Gas Testing (15000psig/1035barg) Low Temperature (-46 C) and Cryogenic Temperature (-196 C) Pressure Testing High Temperature Pressure Testing to 550 C Helium Leak Testing (Mass Spectrometer) Tensile / Bend / Impact / Hardness / Testing Corrosion Testing Metallography Magnetic Particle Dye Penetrant Ultrasonic Examination Radiography Chemical Analysis Alloy Verification / Positive Material Identification (PMI) Feritscope Verification CMM Measurement Laser Measurement
