Product Description

Product Description

API 6C PTFE U-Packing Gate Valve Stem Seals 

 

U-packing and stem packing gate valve seals

The U-packing comprises a PTFE jacked bonded securely with the NBR or FKM/FPM energizer.
Used for Cameron FC gate valves and FL gate valves.

Stem packings, also known as u packing, are designed to be placed between the stem and bonnet of Type FC gate valves. This stem packing gives you a reliable seal for superior performance. This U-packing shell is made of virgin PTFE and the filler could be NBR, HNBR or FKM/FPM. U-packing is used in FC valve.

The different shape of spring seal/ spring energized seal

1.V-spring seals are designed for used in high or low presseure dynamic reciprocationg or rotary applications.

2.Slanted Coil Spring Seals are for low friction, dynamic reciprocating and rotary applications. The seal produces a near flat load curve when compressed ( installed ). They provide constant predictable loads through their very wide deflection range.

3.Helical Spring seals are designed for used in static or slow, infrequent dynamic sealing application due to high compression load over a small deflection range, which make these seals suitable when low pressure or vacuum and very low temperature ( cryogenic ) are present.
