Product Introduction
The DIN F4/F5 Non-Rising Stem Metal Seat Gate Valve is a robust and reliable valve designed for industrial and water supply applications requiring tight shut-off and long service life. Built in accordance with DIN standards (DIN 3202 F4/F5), this valve provides high performance and durability under various operating conditions.
The non-rising stem design makes it ideal for installations with limited space, as the stem does not move vertically while operating. The metal-to-metal sealing structure ensures excellent sealing performance and wear resistance, even under high pressure or high-temperature environments.
The valve body is typically made of ductile iron (GGG40/50), with stainless steel or bronze seats and wedge surfaces to enhance corrosion resistance and extend lifespan. The valve can be operated manually (handwheel), or equipped with electric, pneumatic, or gearbox actuators for automation systems.
