Wika is a world leader in the manufacture of mechanical pressure measuring instruments. We offer a wide variety of instruments, suitable for each sector and each type of pressure. Pressure measuring instruments that indicate gauge pressure, absolute pressure or differential pressure have been tested millions of times.
When a mechanical pressure gauge is used to measure pressure, and the gauge fails, it is impossible to change it without stopping the line. Needle valves are the ideal solution to allow the replacement of a pressure gauge while the line is in operation. For these valves, it is advisable to use those with purge, because it facilitates the operation of the line.
Needle valves, due to their construction, allow flow to be regulated and have an airtight seal. They are manufactured in different materials, the most common being 304, 304L, 316 and 316 stainless steel, carbon steel or special alloys. The connection to the process is normally threaded in ¼” and ½”; The instrument threads the valve in those same diameters.
When using smart transmitters to measure pressure, needle valves or manifolds should always be used, which are nothing more than 2 or up to 5 integrated valves, with their respective drains, in a solid block and interconnected. Manifolds are the indicated solution to connect instruments that measure pressure and be able to interact in setting, maintenance, draining, testing or changing operations of one or more transmitters. They can be connected directly to the process or through tubing to one or more points.
Flexilatina has for the Colombian market, apart from the Wika brand, other brands that offer a variety in selection and/or price, such as Winters or Zaes.
