Change-over to Availability with LESER's New Change-over Valve 

PERFECT SOLUTION
FOR VARIOUS REQUIREMENTS

Challenges: The design of a spare relief valve installation needs to ensure a maximum permissible inlet pressure drop at 3% of the safety valve’s set pressure. This especially should be ensured when dealing with additional piping components, long inlet lines or in combination with high capacity safety valves. Many solutions available in the market need unstandardized modifications in order to adapt to plant conditions, making the pressure drop calculation difficult, sometimes even impossible.

LESER’s solution: To suit a wide variety of application requirements, our new Change-over Valve is available in two types. Both designs have an improved flow path that minimizes the inlet pressure drop. Type 330 Compact is adapted to pressure drop requirements in basic applications. Type 320 Flow fulfills more demanding pressure drop requirements. In addition, the size of the plant piping on the respective system is no challenge for LESER’s Change-over Valve: Its inlet nozzle can easily be adapted to our customers’ needs.
