2022. 8. 1. · Equation 6 : pressure safety valve required discharge area in the case of steam. The correction factor K N can be calculated the following way : K N = 1 if P 1 ≤ 10339 kPa abs. K N = (0.02764*P 1 -1000) / (0.03324*P 1 -1061) if 10339 ≤ P 1 ≤ 22057 kPa abs. Ksh = superheat steam correction factor.

temperature limits indicated in the P/T diagram of the Product Manual. If in doubt contact factory. Check the valve's functionality on a regular basis. When the valve is used in an end-of-line function, PED Cat-I applications are allowed only. For other categories, contact factory. PRECAUTIONS WARNING For safety reasons, it is important to

Check out our Interactive Pneumatic Circuit Symbols here. Position and Flow Boxes The number of 'position and flow boxes' that make up a valve symbol indicate the number of valve positions. Flow direction is indicated by the arrows in each box. These arrows represent the flow paths the valve provides when it is in each position.
