PN16 / PN25 ELECTRIC & MANUAL BUTTERFLY VALVE – HIGH-TEMPERATURE WATERWORKS SERVICE IN DUBAI U.A.E

DUCTILE IRON PN16 / PN25 ELECTRIC & MANUAL BUTTERFLY VALVE – HIGH-TEMPERATURE WATERWORKS SERVICE

⚙️ PN16 / PN25 Electric & Manual Butterfly Valve – High-Temperature Waterworks Service

MATC PN16 / PN25 Electric & Manual Butterfly Valves are heavy-duty flow-control valves engineered for reliable isolation and flow control in waterworks, industrial utilities, HVAC, cooling-water and process piping systems. Available with electric actuator, manual gearbox or hand-lever operation, these valves combine compact construction, rapid quarter-turn operation and dependable sealing. 💧⚙️

High-temperature configurations can be supplied with seat, disc, stem and sealing materials selected specifically for the required operating temperature and media.

📏 Available Sizes

Typical size range includes DN50 (2″), DN65 (2½”), DN80 (3″), DN100 (4″), DN125 (5″), DN150 (6″), DN200 (8″), DN250 (10″), DN300 (12″), DN350 (14″), DN400 (16″), DN450 (18″), DN500 (20″) and DN600 (24″), with larger project sizes available depending on valve design.

💥 Pressure Ratings

📌 High-temperature rating should not be specified from PN16/PN25 alone. The maximum allowable temperature depends particularly on the seat/elastomer, body, disc, stem, pressure and media. For elevated-temperature water or process service, MATC can supply the valve with a suitable material configuration based on the project specification.

💪 Advantages

  • ⚡ Electric automation available for remote operation and control systems.
  • 🔄 Manual gearbox option provides reliable operation without electrical power.
  • 💧 Excellent solution for large-volume water flow.
  • 📉 Relatively low pressure loss when fully open.
  • 🦋 Compact and lightweight compared with many gate-valve designs.
  • ⏱️ Fast 90° quarter-turn operation.
  • 🔧 Lower installation-space requirement.
  • 🎛️ Suitable for ON/OFF and, with an appropriate design/actuator, modulating applications.
  • 🛡️ Multiple seat and disc materials available for different operating conditions.
  • 💥 PN16 and PN25 options cover a broad range of waterworks requirements.
  • 🤖 Easy integration into automated pumping and process-control systems.
  • 🏗️ Well suited to large-diameter infrastructure pipelines.

⚠️ Disadvantages / Considerations

  • 🌡️ Standard EPDM or NBR seats have temperature limitations; genuinely high-temperature applications require appropriate seat selection.
  • ⚡ Electric actuators require a suitable electrical supply and environmental/IP protection.
  • 🔧 Actuator sizing must consider valve torque, pressure differential and safety factor.
  • 💧 The butterfly disc remains within the flow path even when fully open.
  • 📐 Correct alignment is essential during installation to prevent disc/seat damage.
  • 🧪 Material compatibility must be checked for chemicals, seawater or other aggressive media.
  • 🎛️ For continuous precision throttling, the valve and actuator should be specifically selected for control duty.
