Sleeved Plug Valves Manufacturers in India
RFL’s PTFE Sleeved Plug Valves are primarily ON/OFF valves designed for efficient handling of highly corrosive process mediums. They provide effective sealing in low pressure service. Sleeve are made from PTFE that acts as self -lubricant and hence, a maintenance free “fit and forget” valve. RFL’s Sleeved Plug Valves comes in different models, end connections, operations and are qualified for fire safe and low fugitive emission standards as per latest editions.
Types of Valves
1. Inverted Sleeved Plug Valves (ISPV)
In “Inverted Sleeved Plug Valves the plug is located inside the body in a reverse position with the larger diameter resting at the bottom side. The major advantage being the complete avoidance of Plug Jamming & lower operating torques. “The plug as in normal sleeved plug valve designs, are completely encircled within a press fitted PTFE sleeve. The Stem / Shank is a separate member which engages with a drive slot in the plug.
The advantage being the stem can be made of higher strength bar / forgings, thereby enhancing the stem life that of stem housing and sealing life.
The goodness of triple sealing features are incorporated, in the Inverted Sleeve Plug Valves as well. PTFE Chevron packing are provided to make the valve meet stringent Fugitive Emission Norms.
2. Sleeved Plug Valves – DEAD MAN HANDLE
These are also known as spring return handle valves. The special handle ensures that the valve will always “spring return” to its original starting position, when hand / manual effort is released. This type of valve finds vast application in critical service were the valve has to be quickly returned to the original position once a manual operation is completed. These valves assure safety and avoid unnecessary wastage, of costly medium, whenever the valve is allowed to remain in partially opened or closed position, inadvertently.
3. Sleeved Plug Valves – EXTENDED STEM
RFL can supply valves with extended stem. The main purpose of such designs are to isolate the gland from the high or low temperature zone. These valves are predominantly used in places where the valves are not in close proximity with the operator
e.g.: valve located under water, toxic environment, hot pipe line
4. Sleeved Plug Valves – FULL BORE
These are also known as spring return handle valves. The special handle ensures that the valve will always “spring return” to its original starting position, when hand / manual effort is released. This type of valve finds vast application in critical service were the valve has to be quickly returned to the original position once a manual operation is completed. These valves assure safety and avoid unnecessary wastage, of costly medium, whenever the valve is allowed to remain in partially opened or closed position, inadvertently.
5. Sleeved Plug Valves – Jacketed
Jacketed valves are mainly used to handle complex fluid applications such as Tar, Molten Sulphur, adhesives etc. The jacketed valve is specially designed for circulation of hot liquids/gases. It has outlet connections for proper jacket drainage and the oversized flanges are in accordance to international standard.
