Neway Valve

Dubai, United Arab Emirates

Neway cryogenic ball valve is suitable for service of working temperature down to 196, such as LNG, LPG, and air separation industry. Neway cryogenic trunnion ball valves are produced by the most advanced technology. It is designed with LIP SEAL which can keep valves with excellent sealing performance in ultra-low temperature. Neway modern cryogenic test laboratory can test valves up to 48in.

Compared with soft seal ball valves, Neway metal-to-metal ball valves have wider working temperature and medium range. During working condition, it has the features of reliable and safe sealing performance, long service life, easy operation and less pressure loss. Its mainly used in service of high temperature, high pressure, severe corrosion and solid material containing services, such as coal chemical, polysilicon and vitriol/ nitric acid industry.

Neway trunnion mounted ball valves are designed in accordance with API6D featuring 2 pc or 3 pc split body side entry or top entry design. Wide range of sealing material including PTFE, Peek, Devlon, Nylon etc, valve can be used in working temperature range -46 500. This series of valves are optional designed with Double block and bleed or double piston type. All valves are equipped with sealant injection system for both stem and seats to allow external intervention to prevent seat or stem leakage. The top entry ball valve can be used for in-line maintenance services. Neway full range of trunnion mounted ball valves is fire safe test certified by Llodys Register per API607 and API6FA.

Neway trunnion mounted ball valves include:
2 pc cast steel side entry
Cast steel top entry
3 pc forge steel side entry

Neway fully welded ball valves are especially designed for gas transportation and storage industries. The fully welded body design can prevent any potential external leakage from connection of body and bonnet. In addition, the forged body with the advantages of consistent grain size and even thickness. Thus it inherently eliminates the conventional casted valve material defects, such as: shrinkage, porosity.
