Description

Product Overview

TIANYU V-Type Motorized Ball Valve: Precision Solution for HVAC Water System Automation

I. Technical Overview

TIANYU V-type motorized ball valve is specially designed for HVAC water systems, covering DN40-DN150 sizes with ISO7005-2 flange connection, suitable for chilled/hot water and neutral liquids. The body uses QT450 ductile iron (tensile strength ≥450MPa), while the V-shape core and stem adopt 304 stainless steel. Seals are 可选 EPDM or FPM, resistant to -5℃~120℃. Supporting 220VAC/24VAC/24VDC power input, it offers control modes including On-Off, 0-10V analog, and 4-20mA signal regulation, meeting flow regulation and emergency shut-off needs in central air conditioning systems under PN16 (1.6MPa) pressure.

II. Core Product Features

(A) V-Shape Core Flow Control

Equal Percentage Flow Characteristic: The V-shape cut achieves a 50:1 regulation ratio, enabling linear flow control within 0~90° rotation for energy-saving in variable flow systems, reducing pressure loss by 20% compared to traditional ball valves;
Low Leakage Sealing: Reinforced PTFE seat with spring preloading ensures leakage ≤0.01% of Kvs (e.g., ≤0.016m³/h for DN100 with Kvs=160m³/h), complying with ISO 5208 Class IV;
High Flow Capacity: DN150 model reaches Kvs=360m³/h, 15% higher than similar valves, saving ~12,000kWh annual pumping energy.

(B) Motorized Drive Advantages

Drive Parameter	Specification	Application
Voltage Range	220VAC/24VAC/24VDC	Compatible with building automation and industrial power systems
Operation Time	≤60s for 25N·m torque model (DN100)	Quick response to HVAC load fluctuations
Protection Class	IP55 (water jet proof)	Moist air conditioning rooms and industrial environments
Overload Protection	Built-in thermal switch, automatic power-off during blocking	Prevents motor burnout, extends service life

(C) Material & Structural Advantages

Ductile Iron Body: QT450 withstands 1.8x pressure of common cast iron, suitable for high-pressure water systems in tall buildings;
Stainless Steel Core: 304 SS core via solution treatment (HRC20-25) offers 3x resistance to water corrosion, with ≤0.05mm wear after 50,000 cycles;
Dual Sealing Design: PTFE seat + EPDM/FPM seals adapt to chilled/hot water alternation, eliminating medium leakage.

III. Manufacturing & Quality Control

(A) Precision Processing

Body Casting: Lost foam casting ensures surface roughness Ra≤12.5μm, UT-tested for internal shrinkage (sensitivity ≥Φ2.0mm), annealed to relieve stress;
Core Machining: 5-axis CNC mills V-shape cut with angle error ≤±0.5°, fit gap with seat ≤0.03mm for sealing precision;
Actuator Assembly: Modular motor-gearbox design with meshing gap ≤0.05mm, no-load noise ≤55dB, built-in limit switches with ±1° positioning accuracy.

(B) End-to-End Quality Control

Pressure Test: 1.5x rated pressure (2.4MPa) hydrostatic test for 30 minutes without leakage;
Function Test: 5,000-cycle simulation with switch time fluctuation ≤5%, signal feedback error ≤±1%;
Certifications: CE, RoHS certified, UL-compliant models available, support SGS third-party inspection.

Application

IV. Application Scenarios

Central AC Water Systems: Chilled water main flow regulation with temperature sensors for 15% energy saving; fan coil branch shut-off within ≤60s to prevent overcooling/overheating;
Industrial Circulating Water: Cooling pump inlet/outlet control, V-core linear regulation for equipment load changes; boiler make-up water shut-off with zero leakage at 1.6MPa;
Domestic Water Supply: High-rise water pressure regulation via equal percentage characteristic; swimming pool circulation on/off with IP55 protection in humid environments.
