Full Bore Stainless Steel 2PC Flanged Ball Valve Size 2"-20"

Full Bore Stainless Steel 2PC Flanged ISO5211 Ball Valve Size 2”-20”

TEKO offers two-piece flanged ball valves that are specially built for zero-leakage sealing when control conditions require valve actuation exceeding 50,000 cycles. Our flanged ball valves have flanges with bolt holes that are used to lock them to matching flanges on the pipe. Gaskets are placed where the flanges connect to provide reliable sealing and prevent potential leaks. Flanges are an excellent means of connecting pipes, pumps, valves, and other components to produce a piping system. Having flanged connections make installation, removal, and cleaning easy.

The valve body is usually made from carbon steel or stainless steel, both are highly corrosion-resistant and temperature-tolerant materials that are great for crucial service conditions. The ball seats can be made from PTFE or RPTFE materials, which have high chemical resistance. They are available in sizes ranging from NPS ½” to NPS 12”.

Features

Full Port for Unobstructed Flow

TEKO flange end ball valve has full bore to ensure there are no obstructions in the flow. It is ideal in applications where low flow resistance and pressure drop are important. Having a full bore means the valves share a similar internal diameter with the pipes, which reduces pressure drop and cavitation. A full bore flanged ball valve is also widely used in media with mixed solids and liquids. This is to prevent build-ups that could affect the flow rate of the pipe

Blow-out Proof Stem
A blow-out proof stem contributes to the integrity of our flanged end ball valves. It means the stem is separated from the valve body to keep it from blowing out. In severe applications, the valve body will receive excessive pressure, which might cause the stem to dislocate. With a blow-out proof design, the stem is secured in place by the stem housing, which is attached to the valve body.

Antistatic Device
An antistatic device helps reduce accidental fire by providing a ground path to keep electrical conductivity between the valve body, ball, and stem. This ensures that the friction caused by valve operation does not cause static build-up. With the antistatic device, our ball valves will not produce sparks that could lead to fires and other accidents.

How Does a Flanged Ball Valve Work

A flanged ball valve is used to shut media flow in both directions. This ball valve type is designed to be compact, simple, and generally the economical solution for flow control operations. It is an excellent alternative to lined-up plug valves and diaphragm valves.

A flanged ball valve operates similar to a typical ball valve. It is a type of quarter-turn valve used to release or obstruct media flow in pipelines. It has a spherical disc, more commonly known as a ball that has a hollow center which rotates to open or close media passage.

The difference is that the flange ball has a control spindle that controls the ball to open and closed positions. When the ball is pushed by system pressure against the side of the non-pressurized seal, the valve shuts the flow with no risks of leaking.
