Brass / Chrome Plated Valve Stem Extension Sleeve Cartridge Extension Customized Size

Specification

What is Valve Cartridge Extension Sleeve ?

Valve Cartridge Extension Sleeve is a key transition accessory in the piping system to solve the problem of insufficient installation space or limited operation. It is especially important in narrow or hidden spaces (such as concealed water tanks and dense pipe wells).

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.)
