Key Functions

1. Operational Extension

   • Extends valve stem length to adapt to confined or hard-to-reach installations (e.g., behind walls, underground pipelines).

   • Enables safe operation in high-temperature or hazardous environments by relocating the actuator/handwheel to accessible areas.

2. Compatibility Enhancement

   • Bridges mismatched interfaces between valves and actuators in retrofit projects.

   • Supports standardized valve systems (ISO 5211, DIN 3338) for multi-brand compatibility.

3. Corrosion & Wear Resistance

   • Chrome plating provides a protective layer against abrasion, chemical exposure, and oxidation, extending service life in humid or corrosive conditions (e.g., marine, chemical plants).

Structural Features

1. Material & Coating

   • Body: High-grade brass (C36000/C37700) for superior machinability and pressure resistance (up to 1.6 MPa).

   • Surface: Electroplated chromium (10–15 μm thickness) for enhanced hardness (800–1000 HV) and smooth operation.

2. Precision Engineering

   • Internal splines/hexagonal bore to prevent stem rotation during operation.

   • Threaded ends (NPT/BSPP) with PTFE sealing tape grooves for leak-proof connections.

3. Customizable Design

   • Available in standard sizes (1/2", 3/4", 1") with on-demand customization for:

     • Anti-vibration slots or thermal expansion joints.

     • Flanged ends for bolted systems.

     
     

Competitive Edge

• Tailored Solutions: DSTHERM’s CNC machining allows ±0.1 mm dimensional accuracy for niche applications.

• Cost Efficiency: Chrome plating reduces maintenance frequency by 40% compared to uncoated brass sleeves.

Applications

Example: A Dubai hotel retrofit project required extending 120 bathroom mixing valves through concrete walls. DSTHERM supplied 300 mm chrome-plated sleeves with M30×1.5 threads, enabling tool-free installation and eliminating post-construction leakage.

For custom specifications, provide valve type (ball/gate/globe), stem diameter, and environmental conditions (temperature/pressure/media).
(Note: Technical parameters can be expanded based on DSTHERM’s actual product data.)
