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.
