seal gate valve F4 / F5 German standard elastic seat seal gate
valve the soft seal gate valve adopts non cavity structure, the
inner and outer surface of valve cover is sprayed with epoxy resin,
and the surface of gate is covered with rubber, which fundamentally
increases the possibility of corrosion. The "O" ring is used
instead of packing at the valve stem seal, which makes the seal
reliable. Design of gate valve:Integral valve cover, Non rising
stem design, compact structure; The valve rod nut and the gate
plate have two-body structure, without jamming; Straight channel,

with rubber which meets the sanitary inspection; The valve stem,
stem nut and other parts are made of stainless steel or bronze
which is not corroded by water. Scope of application:Drinking
water, water supply and drainage, sewage treatment. Technical
