PN16 Two Pieces Stainless Steel 4 Flanged Ball Valve With ISO 5211 Mounting

PN16 Two Pieces Stainless Steel 4 Flange Ball Valve With ISO 5211 Mounting

Description

The flange ball valves are opened and closed by a lever, handle or hand wheel and usually require only a quarter turn before instantly shutting off. Flanged ball valves are made from metals such as stainless steel or brass, making them durable and long-lasting; they retain their function even if they are not used for years. Though generally not used in throttling applications because of the small range of motion of the actuator, incremental opening and closing of the valve is possible

Features:

Construction

The Ball Valves are of a two piece construction and have a solid full bore ball. Relevant design standards are EN ISO 17292, EN 12516, ASME B16.34 and API 608.

Materials

Carbon steel (ASTM A216 WCB) and stainless steel (ASTM A351 CF8M) are the materials which form the standard supply. Other materials can be supplied upon request.

Fire-Safe

In the event of fire, a secondary metallic seat prevents leakage through the valve port. A graphoil stem seal and a graphite spiral wound body gasket with PTFE inner layer ensures tightness through the stem packing and body joints.

Gland Packing

Two Belleville spring washers ensure optimal sealing performance, also compensating for changing process conditions. Advantages of this feature are an increased operational safety and less maintenance. In accordance with fire-safe requirements, the packing material is made of Graphoil.

Anti-static

The ball-stem connection and the stem-body connection have an anti- static feature, which ensures electrical continuity between those parts.

Direct Mount

A Direct Mount top-flange according to ISO 5211 is standard for these Ball Valves. This feature makes it possible to mount an actuator without the need of a mounting bracket and drive adapter. This gives a considerable cost reduction, compact automated unit and a higher level of safety for operators.

Applicable Standards

TEKO Industry Co., Limited, established in 2010, is a rapidly growing industry products manufacturer in China. Throughout 8 years of development, we have been now becoming the major valve supply in industries of petroleum, chemical plant, power station, mining, metallurgy, waste water treatment, shipbuilding etc.

Recently our business scope has covered the industry valves and marine valves, including the gate/globe/check valve, butterfly valve, knife gate valve, pinch valves, high performance butterfly valve, strainer and so on. With our experienced workers, we can now workable with big capacity up to 500 tons per month.

Always bearing in mind “quality first”, we operate production strictly following the ISO9001 regulations. In addition, our valves are hydraulic testing according to the requirements of related standards, such as API598. We ensure that all valves delivered are not satisfy the customer’s requirements, but also exceed their expectation. And we TEKOers truly mean it.

We have engineers with more dozens of years of experiences and that benefit us that we can always updated our valve new technology and new design that can fit most severe fluid services. It is so inspiring after we have handled the tough fluid for our customers, no matter how high temperature/pressure, highly abrasive, highly corrosive is. It also, at the same time, drives us to make progress every single day to offer the best service during the next time.
