Suppliers in the UAE provide an extensive selection of butterfly valves available in wafer, lug, and double-flange configurations, designed for both on/off and modulating control in fluid and gas distribution systems. The materials commonly used include ductile iron, cast iron, stainless steel 316/304, and specialized alloys, with seals made from EPDM, NBR, and Viton to accommodate various media such as water, chemicals, and hydrocarbons.
These valves are manufactured in accordance with international standards such as API 609, ISO 5752, and AWWA C504, rendering them vital for applications in HVAC, water treatment, firefighting, oil & gas, and marine sectors. The services offered include assistance with technical selection, integration of actuation systems (electric/pneumatic), pressure testing, and prompt delivery of both stock and project orders throughout the Emirates.
Typical UAE Price Range (AED):
• Resilient Seat Butterfly Valve (DN50-DN200): 80 – 600 /pc
• Double Eccentric High-Performance Valve (DN50-DN300): 350 – 2,500 /pc
• Triple Eccentric Metal-Seated Valve (DN150-DN600): 1,200 – 12,000+ /pc
• Stainless Steel 316 Wafer Valve (DN50-DN150): 250 – 1,800 /pc
• Pneumatic Actuator Package: 500 – 4,000 /set • Electric Actuator Package: 900 – 8,000+ /set.
Note: Pricing is significantly influenced by factors such as valve size, design (resilient/double/triple eccentric), body/disc material (CI/SS316/Alloy), seat material, pressure rating (PN10/PN16/PN25/Class 150), and whether actuators or gear operators are included.
Butterfly valves are known for their compact design, lightweight nature, and cost efficiency. They function swiftly with a quarter-turn mechanism, require less installation space than gate or globe valves, and are particularly effective for managing substantial flow rates of liquids and gases.
The selection process is influenced by the type of fluid or gas, pressure, temperature, and the intended function. For HVAC systems and water applications, a resilient seat valve is typically used. In contrast, for oil and gas applications or high-temperature steam, a high-performance double or triple-eccentric metal-seated valve is essential.
Leaks are frequently attributed to a degraded elastomer seat, debris blocking the seal, or improper closure of the disc. To resolve this issue, one usually needs to clean the valve, re-center the disc, or replace the seat. In the challenging conditions of the UAE, exposure to chemical or abrasive substances can hasten the wear of the seat.
PN16 refers to "Pressure Nominal 16," indicating that the valve is rated for 16 bar of pressure at ambient temperature. Class 150 represents an ANSI rating for 150 PSI at a designated temperature. It is crucial to ensure that the valve's pressure rating is higher than the maximum operating pressure of your system.
