Product catalog summary
Overview: This document provides technical specifications and details for continuous blow down valves used in steam boilers. These valves are designed for automatic and continuous removal of impurities from boiler water to maintain efficiency and safety.
Specifications:
  • Nominal Diameter: DN 15, 20, 25, 40
  • Nominal Pressure: PN 40
  • Design: Two-way design with or without sample valve
  • Material: Valve body made of GP-240-GH
  • Features: Hardened cone and seat for low wear operation, parabolic cone with linear characteristic for precise flow rate adjustment
Technical Data:
  • Spindle Packing: Chevron rings PTFE/graphite (up to 250°C)
  • Cone Type: Parabolic cone
  • Kvs-Values: Refer to Table 1
  • Max Pressure/Temperature: According to DIN EN 1092
  • Materials: Detailed in the spare parts list
