Typical Applications & Valve Types

Engineered exclusively for high-volume fluid control components.

🔴 Gate Valve Bodies

  • Simultaneous facing of both wedge sealing surfaces
  • Zero clamping error—guarantees perfect concentricity
  • Accommodates 1/2″–2″ (DN15–DN50) sizes

🟡 Brass CW617N Ball Valves

  • Ideal for CW617N, C36000 brass alloys
  • High-speed threading and internal profiling
  • Minimal burr, exceptionally clean finishes

🔵 Check Valve Bodies

  • Precision machining for internal check components
  • Multi-step profiling and threading operations
  • Automated loading ready for unattended runs

Why Upgrade to a Dual-Head CNC Machine?

In traditional single-head turning, machining a valve requires doing one side, stopping the spindle, unclamp the hot part, flip it, re-clamp it, and machine the other side. This process is slow and introduces concentricity errors. The HC-RTB-25-K features a vertical central clamping mechanism and two opposed horizontal spindles. It machines both ends of the valve body simultaneously in a single setup. This guarantees perfect concentricity, eliminates re-fixturing time, and effectively doubles your production output.

1 Setup = 2 Ends Machined Perfect Concentricity 50% Cycle Time Reduction

Frequently Asked Questions

What is the time-saving advantage of dual-end machining?

The dual-head configuration eliminates spindle stopping, un-clamping, flipping, and re-clamping. Both ends of the valve body are machined simultaneously in one single setup. This effectively cuts your cycle time in half compared to traditional single-head CNC lathes.

What control system does the HC-RTB-25-K use?

The standard machine utilizes a Yitu 4-Axis Dual-Channel CNC system. It supports standard ISO G-code programming, features an industrial touchscreen interface, and has an Ethernet port for remote access and factory network integration.

What is the maximum valve body diameter it can handle?

This SPM is specifically designed for fluid control applications in the 1/2″ to 2″ (DN15 to DN50) size range. It can easily accommodate raw forgings and castings up to 40mm in diameter.

Can it integrate with an automatic loading system?

Absolutely. The HC-RTB-25-K features a standard M-code interface specifically designed to communicate with vibratory bowl feeders, gantry loaders, or robotic arms for fully unattended 24/7 valve production.
