PTFE Sleeved Plug Valve

Rasaii is an exclusive manufacturer of various Teflon Sleeved Plug valves. The PTFE Sleeved Plug valves are a replacement for Lubricated Plug Valve, Ball Valve and Teflon Lined Plug Valve The CI valve flanges have a flat face. Max working temperature for the PTFE Sleeved Plug Valves is well around 2000C. Static Eliminator will be provided wherever necessary.The PTFE Sleeved Plug Valves from Rasaii are maintenance free and Non-Lubricated. The Teflon Sleeved Plug Valves are available in 6” and above dimension, with a screwed end and an actuator also.

Teflon Lined Plug Valve

This is the best selection for highly corrosive media being metal price is fluctuating frequently and the price is not stable even for 2 months. In that condition, the Lined valves are the best replacement for Metallic high alloy valves. The Inventory will be very limited being your selection is PFA/FEP (Teflon Lined) to withstand any chemicals including mixed acid. Teflon Lined Plug Valve from Rasaii comes in 6” or more size. Maximum operable temperature range is 1800C. End connections are designed in accordance with ANSI 150, ASA 150, B 16.5 standards. All lined portion of the valve is spark tested to about 10KV.

Teflon Lined Ball Valve

The Teflon lined Ball Valve is similar to the above valve, and is also a best replacement for Metallic Ball Valve as the life will be extremely good due to the design such as ball and stem are Integral part can be used in any chemicals. The Teflon Lined Ball Valve comes as a 2 piece or a three piece unit with FEP or PFA lining. Operating temperature range is same as Teflon Lined Plug Valve, 1800C and all the linings are tested with about 10KV high volt shocks.

Teflon Lined Check Valve (Puppet type)

The Puppet type Teflon lined Check Valve has a taper design that works effectively in back pressure. This design is unlike the spherical or Ball type design which eventually loses shape after few months of operation. The puppet type check valve will never get damage rather it will form into better a taper portion than before. Rasaii’s Teflon lined Check valve has several other features like a full port, unidirectional flow, low pressure dropping, better corrosion resistance than steel & alloys, liner is locked by grooves permitted the check valve to be used on high vaccum & pressure applications without line collapse and blow out, they economically handle corrosive or high - purity flow media.
