The MT Series wafer butterfly valves pair a ductile iron GGG50 body (EN 1563) with a stainless steel AISI 316 disc and field-replaceable EPDM or NBR seat, covering DN50 to DN300 for water treatment, chilled water distribution and industrial process service across UAE infrastructure. Quarter-turn lever or gearbox operation provides fast, low-torque isolation; wafer face-to-face dimensions fit between EN 1092-2 flanges to minimise installation space. CE · ACS certified, stocked in Dubai.

Frequently Asked Questions
What is a wafer-type butterfly valve and how does it install between flanges?
A wafer-type butterfly valve has no integral flanges — it clamps between two pipe flanges using long bolts that pass through the valve body. This makes it lighter and more compact than lug-type valves, ideal for tight plant rooms. MT butterfly valves comply with EN 558 face-to-face dimensions, compatible with EN 1092-1 flanges used across UAE and GCC projects.
What is the maximum pressure and temperature rating?
MT wafer butterfly valves are rated PN10/PN16 depending on size. The EPDM seat suits -10 °C to +120 °C, making them ideal for chilled water, HVAC, fire-fighting, and general utility water. For steam or high-temperature service, PTFE-seated versions are available on request.
Are these butterfly valves suitable for potable water in the UAE?
Yes. The EPDM elastomer seat is approved for drinking water contact (WRAS / KTW / ACS). The stainless-steel disc is compatible with desalinated water. These valves are widely used in UAE building water systems, district cooling plants, and municipality infrastructure.
What actuator options are available for automated control?
MT butterfly valves feature an ISO 5211 actuator pad as standard, making them directly compatible with pneumatic, electric, and hydraulic actuators without a bracket adapter. MT Middle East can supply valve-actuator packages ready for installation — contact us with your Cv, fail-safe requirement, and control signal.
What are delivery lead times from Dubai stock?
Standard sizes (2" to 8") are stocked in Dubai for same or next business day dispatch. Larger sizes and actuator packages are available on short lead times. Contact MT Middle East for project scheduling and volume pricing.
