Quick Overview
The double half shaft butterfly valve rated at 150LB is designed for projects where cost control, structural reliability, and stable sealing performance must be balanced. Manufactured by Vcore Valve, this valve configuration is widely applied in water supply, HVAC, and general industrial pipeline systems. By optimising shaft structure and reducing unnecessary material usage, it delivers dependable fluid control at a competitive price point.
A Real-World Scenario
“Is there a butterfly valve that meets Class 150 requirements without inflating the budget?”
This question frequently comes from contractors and project managers. In many cases, the answer lies not in cutting quality, but in choosing a smarter design. The double half shaft butterfly valve is engineered precisely for this purpose—efficient, practical, and economical.
Key Challenges Faced by Users
High Procurement Costs
Traditional full-shaft butterfly valves often involve higher material consumption and machining complexity.
Structural Imbalance in Low-Cost Valves
Some low-priced valves suffer from disc misalignment and uneven torque distribution, leading to leakage risks.
Consistent Compliance with Class 150
Users require 150LB butterfly valves that reliably meet pressure standards without sacrificing service life.
Practical Solutions Offered by Vcore Valve
Optimised Double Half Shaft Design
The dual half-shaft structure supports the disc from both sides, improving stability during operation.
Reduced Manufacturing Complexity
Shorter shafts and simplified machining reduce cost while maintaining mechanical integrity.
Flexible Installation Options
Available in wafer butterfly valve and lug butterfly valve types, suitable for various pipeline layouts.
Application Case Examples
Municipal Water Pipeline
In a regional water distribution project, 150LB butterfly valves with double half shafts replaced gate valves, reducing installation time and overall system cost.
Commercial HVAC System
A large commercial building adopted resilient seat butterfly valves, achieving smoother operation and lower actuator torque requirements.
Technical Comparison and Performance Data
| Parameter | Full Shaft Butterfly Valve | Double Half Shaft Butterfly Valve |
|---|---|---|
| Material Consumption | Higher | Lower |
| Structural Balance | Standard | Improved |
| Manufacturing Cost | Higher | More economical |
| Pressure Rating | Class 150 | Class 150 |
| Typical Applications | Industrial | Water & HVAC |
From an engineering standpoint, the double half shaft butterfly valve provides a rational solution for fluid control valve systems operating under moderate pressure conditions.
