Control Valves ZK

Product catalog summary

Overview: The document provides technical specifications and applications for Control Valves ZK with Radial Stage Nozzle, specifically models ZK 29/14 DN 50 and ZK 213. These valves are designed for managing high-pressure drops in industrial plants and power stations.

Applications: The valves are suitable for various applications including level control, warm-up, injection cooling, feedwater control, leak-off, and start-up pot drain valves.

Features: Key features include extreme wear resistance, excellent sealing and control characteristics (EN 12266-1 Leckrate A), variable valve characteristics (linear and equal-percentage), easy assembly and inspection of nozzle inserts, tandem shut-off for specific models, low sound levels, and availability of different actuators.

Materials: The document lists materials used for different valve types, including 13 CrMo 4 4, GS-17 CrMo 5 5, 16 Mo 3, A182 F1, 10 CrMo 9 10, and X 10 CrMo VNb 9 1, with options for butt-weld ends of other materials.

Actuators: Various actuator types are available, including handwheel, electric rotary and linear actuators, electro-hydraulic linear actuators, pneumatic actuators, and part-turn actuators, depending on the valve model.

Technical Data: The document provides detailed Kvs-values (m3/h) for different valve designs and pressure/temperature ratings. It includes data for straight-through/angle and Z-pattern configurations, with specific values for pressure drops (∆p) at various bar levels.

Additional Models: The ZK 610 and ZK 613 models are highlighted for large flow rates, featuring a modular assembly principle, low sound levels, and a leakage-free pressure-balanced design. The Kvs range for these models is from 18 to 969 m3/h, with detailed technical data for different stages of expansion.
