MALTEK Trading as Stockist and Supplier of Extended Stem Butterfly Valves

Overview: MALTEK Trading is a prominent stockist and supplier of Extended Stem Butterfly Valves, offering a range of high-quality valve solutions for industrial applications. These valves are used for controlling the flow of liquids, gases, and slurries in pipelines. 
Technical Description of Extended Stem Butterfly Valve:

1. Valve Type:

   • Butterfly Valve: A quarter-turn rotational valve used for regulating flow in pipelines. The valve disc rotates around an axis, with the stem extending to a mechanism outside the pipeline for actuation.

2. Extended Stem:

   • The valve comes with a longer stem that allows for the operation of the valve above ground or from a distance, particularly useful when the valve is installed in systems with insulation, high-temperature applications, or difficult-to-reach locations.

3. Materials of Construction:

   • Body Material: Cast iron, ductile iron, stainless steel, or carbon steel (depending on the application and fluid type).
   • Disc Material: Stainless steel or other alloy options, depending on the corrosive nature of the flow medium.
   • Stem Material: Stainless steel or alloy steel for added strength and durability.
   • Seat Material: EPDM, NBR, Viton, or PTFE, which offer superior sealing properties and are chosen based on temperature and chemical compatibility.

4. Design Features:

   • Flow Control: The butterfly valve is designed to provide tight shut-off and excellent flow control with minimal pressure drop.
   • Size Range: Typically from 2 inches to 60 inches or larger, based on the required application.
   • Pressure Rating: Ranges from 150 psi to 600 psi, with specific models designed for higher pressure systems.
   • Actuation: Manual, electric, pneumatic, or hydraulic actuators can be attached, depending on the operational requirements.

5. Applications:

   • Water & Wastewater Treatment: Used for regulating water flow and in systems with high pressure.
   • Oil & Gas: Extended stem valves are crucial in pipelines with insulation or high-pressure systems.
   • Chemical Processing: Handles corrosive fluids where high resistance is necessary.
   • HVAC Systems: For controlling airflow in large commercial or industrial buildings.
   • Food & Beverage: Where hygienic applications are required, valves come with FDA-approved materials.

6. Sealing Mechanism:

   • A high-performance seat design ensures excellent sealing, preventing any leakage in the system.
   • The extended stem allows the valve to be operated without direct access to the pipe, ideal for extreme conditions.

7. Temperature Range:

   • Depending on the materials chosen for the valve, extended stem butterfly valves can operate at temperatures ranging from -50°C to 350°C (-58°F to 662°F).

8. Advantages:

   • Compact Design: Saves space in confined areas while maintaining excellent control over flow.
   • Cost-Effective: Lower initial costs and minimal maintenance required.
   • Easy to Install and Operate: Simple quarter-turn operation and easily configurable for remote actuation.
