Symbol Symbol used in catalogs and application descriptions Symbol used in diagrams There are no standard symbols for PICVs in diagrams Recommendation ● A strainer or dirt trap should be fitted upstream of the valve to enhance reliability and service life. ● Remove dirt, welding beads etc. from valves and pipes. ● Do not insulate the actuator bracket, as air circulation must be ensured! Mounting ● ● PICV and actuator can easily be assembled on site.
VPF44.. ( 8 mm, V [m /h]) 3 VPF44.. has a symmetric pre-setting scale for easy commissioning. Identical pre-settings positions give identical flow rate. Volumetric flow V / V100 Valve characteristic Stroke H / H100 Working pressure [bar] Working pressure and medium temperature Medium temperature [℃] Working pressure and medium temperature staged as per ISO 7005. WARNING Current local legislation must be observed.
Commissioning NOTICE ● ● ● ● Consequences The valves must be commissioned with the actuator correctly fitted. Strong pressure impacts can damage closed PICVs. The valves must be open when flushing or pressure testing the system. Strong pressure impacts can damage closed PICVs. Differential pressure Pmax across the valve’s control path is not allowed to exceed 600 kPa. Valve’s factory default position = CLOSED. Maintenance The VPF43..PICVs are maintenance-free.
