Butterfly Valve K4

Product catalog summary

General Specifications:
The Butterfly Valve K4 is designed with sealing materials EPDM and FPM, and a body made of PP-GF. The disc materials include PVC-U, PP, and PVDF. It supports dimensions ranging from DN65 to DN200 and flange connections according to DIN 2501, ANSI B 16.5, JIS 10 K (for DN65-DN150), and BS Table D&E. The operation pressure for PVC-U, PP, and PVDF is PN 10.

Actuator Specifications:
The actuators are categorized into ER (plastic body) and VS (plastic aluminum body). The ER actuators are suitable for butterfly valves DN65-DN125, while VS actuators are for DN150-DN200. Key features include a double-sealed shaft, integrated bracket for mounting, mechanical limit stops, emergency manual override, and protection classes ER IP65 and VS IP67.

Dimensions and Torque:
The document provides detailed dimensions for each actuator type (ER35, ER60, ER100, VS150, VS300) and the corresponding butterfly valve sizes. It also includes torque specifications and tightening torque for flange connections.

Installation Guidelines:
For proper installation, the document specifies the necessary inner diameters for sockets and stub flanges to ensure complete opening of the valve flap.

Technical Data for Actuators:
The ER actuators have torques of 35Nm and 60Nm, while the VS actuators have 150Nm and 300Nm. They operate on various voltage ranges and have different operating times and power requirements. The VS actuator includes an integrated anti-condensation heater and has a duty cycle of 50%, while the ER actuator has a duty cycle of 30%.

Diagrams and Charts:
The document includes flow characteristics, pressure-temperature diagrams, and pressure loss diagrams, providing insights into the valve's performance under different conditions.
