  • Checking rotary valve clearances

    Rotary valves are precisely machined to accommodate very tight internal clearances. In a smaller standard valve there should be a .003” – .005” gap between the tips and ends of the rotor and the housing / headplate. However, the clearances on many valves are customized to meet the needs of a specific application. For example, in applications with temperature greater than ...

  • Installation Steps of Sanitary Ball Valve

    The sanitary ball valve uses a special molding process to allow a dense sealing surface to achieve zero leakage. Its sphere and shank are fused as one to remove the valve stem from pressure due to pressure changes within the possibility of pressure pieces and, therefore, achieve the fundamental guarantee of safety. It uses a full metal hard welding process that is resistant to strong corrosion. ...

  • Sanitary Ball Valve Requirements and Maintenance

    Regarding the requirements of sanitary valves, the most important requirement is their material because it is in direct contact with the flow of the media. In general, sanitary tap materials are made of stainless steel and the two main materials are 304 and 316L. These two stainless sheets of steel are the most resistant to corrosion. As a result, they will not easily ...

  • Learining how to Choose Materials for Gas Valves

    The materials and the quality of gas valves are so important that their disqualification will lead to leakage in-or-outside the body of the valve. If the strength, rigidity and overall performance of the components of the valve body cannot meet the requirements or even break, it will result in the spillage of gas and explosion. Therefore, material and quality are the most critical part during the ...
