Control valves for regulating flow/circulation MV 5241/ MV 5341 PV 6241/ PV 6341

Product catalog summary

Overview: This document provides technical specifications and functional descriptions for control valves used in discharge and recirculation systems for water or air-cooled condensers. It covers both electric and pneumatic series, specifically the MV 5241, MV 5341, PV 6241, and PV 6341 models.

Specifications:

Nominal Diameter: DN 50 to 150
Nominal Pressure: PN 16 to 40
Body Material: GP-240 GH, GJS-400-18-LT, GX5CrNiMo19-11-2
Design: Three-way valve with adjustable Kvs value in gate B and a cone that can rotate 80°
Flanges: Connections according to DIN 2501 and ANSI RF standards
Spindle Packing: PTFE/graphite up to 250°C, pure graphite up to 400°C

Functional Characteristics:

The actuator adjusts a cone fitting to control discharge quantity, maintaining minimum flow in the condensate pump.
Fine adjustment of recirculation quantity is possible during commissioning.
Optional variant allows proportional decrease in circulation flow as discharge flow increases.

Technical Data:

Cone Types: Diverting cone for flow/recirculation control
Trim Materials: Spindle and seat made of 1.4571, parabolic and perforated cones made of 1.4122
Seat Leakage: Outlet A: 0.005% of Kvs value, Outlet B: 0.1% of Kvs value
Max Pressure/Temperature: According to DIN EN 1092

Diagrams and Tables:

Diagrams illustrate Kvs value progression for discharge and recirculation.
Table 1 provides Kvs values for different DN sizes and configurations.

Spare Parts List: Detailed list of components including housing, flange group, cone assembly, spindle packing, and more, with materials specified for each part.

Dimensions: Dimension sheets for various models and configurations, including weight and size specifications.
