Maria Valve
1 / 5
ISO-Certified Resilient Seated Gate Valves for Water Supply, HVAC, Fire Protection and Industrial Systems
The valve controls fluid flow by raising or lowering the wedge gate through the rotating stem. When the handwheel is turned, the stem drives the gate to move vertically. In the fully open position, the gate is completely lifted out of the flow path to minimize resistance; when closed, the resilient wedge tightly contacts the seat to achieve complete shutoff. This simple and reliable mechanism ensures stable on/off control in various pipeline systems.
Every valve is fully pressure tested on both shell and seat before delivery to guarantee safety and reliability. Resilient seated design delivers bubble-tight shutoff with zero leakage under rated pressure. Robust ductile iron construction offers excellent strength and long service life. Low flow resistance when fully open helps reduce energy consumption.
