The Super Austenitic UB6 or SS 904L Plug Valve, also known by material codes UNS N08904 and DIN 1.4539, is a high-alloy austenitic stainless steel plug valve. It boasts low carbon content and exceptional corrosion resistance, particularly in dilute sulfuric acid environments. Designed for harsh corrosion conditions, it features high chromium and sufficient nickel content. The addition of copper enhances its acid resistance, especially against chloride gap corrosion and stress corrosion cracking, minimizing corrosion spots and cracks. With slightly better pitting resistance than other steels, it offers good machinability and weldability, making it suitable for use in pressure vessels.

The PTFE-sleeved plug valve, according to ANSI standards, is suitable for cutting and connecting pipeline mediums in industries such as petroleum, chemical, pharmaceuticals, chemical fertilizers, and power generation. It operates under nominal pressures ranging from Class 150 to 900LB and temperatures from -29 to 180°C.

PTFE Sleeved Plug Valve-Feature

1. The product features a rational structure, dependable sealing, outstanding performance, and an appealing design. 
2. Its sealing is achieved by the sleeve's surrounding sealing face, boasting a unique 360-degree metal edge for sleeve protection and fixation. 
3. With no cavities for medium accumulation, the valve ensures cleanliness and is suitable for environments prone to stickiness. 
4. Its dual-direction flow capability facilitates easy installation and use. 
5. It offers a bi-directional, bubble-tight seal unaffected by line pressure and incorporates a static electricity eliminator in constant contact with the plug, ensuring safety in liquid media.
