Application Description

Installing BWTX ON/OFF motorized butterfly valves in cooling tower inlet pipes enables seasonal system switching. A BSPX static balancing valve ensures balanced resistance across branch pipes, optimizing flow. Additionally, a temperature-controlled bypass regulating valve group stabilizes water temperature between supply and return, enhancing cooling efficiency.

BWAX Modulating Type Motorized Wafer Butterfly Valve

Superior Sealing: Excellent sealing performance with minimal water head loss.
Durable Design: Floating, wide-sided rubber seat ensures long-lasting use.
Enhanced Reliability: Long through-shaft design provides added strength.
Advanced Motor Protection: Planetary gear motor includes temperature overload protection.
Flexible Operation: Manual/electric switch offers operational versatility.
Environmental Resistance: IP67 protection grade ensures durability in challenging conditions.

BSPX Static Balancing Valve

Variable Orifice Design: Enables coarse tuning via preset adjustments.
Self-Balancing Cartridge: Low-torque adjustments and reliable shutoff performance.
Y-Shaped Body Structure: Offers a wide flow adjustment range.
Zero Leakage: Floating O-ring ensures no leakage at the fully closed position.
Built-in Memory Device: Allows adjustable and lockable maximum opening settings.
Easy Installation and Debugging: Top-positioned adjustment handwheel for user convenience.

Application Description

The circulating pump station of the HVAC system is different from the general water supply pump station. It has the characteristics of low pump head, large diameter and long-term operation.

BRVB Nozzle Type Check Valve 

Quick-Closing Structure: Lightweight valve plate with spring-assisted closing eliminates water hammer impact and noise.
Axial Flow Design: Built-in nozzle-type flow guide minimizes head loss.
Stainless-Steel Metal Seal: DN300 and above feature durable seals with zero leakage.
Shaftless Design: DN300 and above prevent jamming during operation.
Maintenance-Free Operation: Requires no regular maintenance.
Flexible Installation: Can be installed in any position following the flow arrow direction.

Application Description

By installing a pressure differential bypass regulating valve group in the bypass pipe between the water distributor and the water collector, the pressure difference between the chilled water supply and return can be stabilized. The valve group can consist of a BWAX modulating motorized wafer butterfly valve, a differential pressure sensor, and a PID controller, or an A800 self-operated differential pressure bypass control valve.

Installation

On the Return Pipe of the Water Collector:
Initial Operation: Limits flow during initial operation and debugging.
Normal Operation: Allows flow measurement for each brand system.
On the Supply Pipeline in the Tube Well:

Achieves regional maximum flow settings and features a constant pressure difference function.
Functionality:

Enhances operational efficiency by maintaining designed flow rates and system balance.
Enables precise measurements for troubleshooting and system optimization.

PDRV Dynamic Balancing Valve 

Integration with BSPX Valve: Installed on the tube well return pipeline to maintain regional pressure balance between supply and return pipelines.
Hydraulic Control Operation: Requires no external driving force for functionality.
Simple and Reliable Design: A single moving part in the main valve ensures a low failure rate.
Friction-Free Diaphragm Structure: Eliminates friction for high control sensitivity.
Adjustable Pressure Difference: Control ranges from 20 kPa to 150 kPa for flexible application.
High Control Accuracy: Maintains pressure difference within ±5%.
