The core parts of the Best DIN3352 F4 resilient seated gate valve mainly include valve body, bonnet, stem and gate.The sealing of the whole Best DIN3352 F4 resilient seated gate valve mainly depends on the contact between the rubber gate and the casting. The rubber has a small amount of elastic deformation due to stress to achieve good sealing effect. The sealing is reliable, and can achieve zero leakage. The friction coefficient is very small, the wear is small, the torque of the valve is small when it is opened and closed, the operation is light, the service life is long, no pollution, corrosion resistance and the appearance is beautiful.

The friction coefficient is very small, the wear is small, the torque of the valve is small when it is opened and closed, the operation is light, the service life is long, no pollution, corrosion resistance and the appearance is beautiful.

The Best DIN3352 F4 resilient seated gate valve adopts the flat bottom design with no groove at the bottom of the inner cavity and the same bottom as the water pipe, so it is not easy to cause debris deposition and the seal is consistent.

The ram of Best DIN3352 F4 resilient seated gate valve adopts high-quality rubber for integral inner and outer packing. The vulcanization technology of rubber ensures the geometric dimension of the RAM after vulcanization, and the rubber is firmly attached to the ductile iron, which is not easy to fall off and has good elastic memory.

The valve body, bonnet, support, handwheel, transmission cap and other parts of the Best DIN3352 F4 resilient seated gate valve are made of nodular iron. After special treatment, the high-pressure electrostatic spraying technology is used to spray epoxy powder coating on the inner and outer surfaces. The inner parts are made of stainless steel or copper alloy, thus effectively preventing the formation of corrosion, and has no pollution, no toxicity and beautiful surface.

Because of the spray coating technology, the surface of epoxy resin coating is very smooth, which greatly reduces the surface roughness of the passage through which the medium flows, so the flow resistance is small and the head loss is less; At the same time, the design of the bottom of the valve body is straight through type, which also reduces the flow resistance and head loss.

Due to the application of spraying technology, the surface of epoxy resin coating on the Best DIN3352 F4 resilient seated gate valve is very smooth, which greatly reduces the surface roughness of the channel through which the medium flows, so the flow resistance is small and the head loss is small; At the same time, the bottom of the valve body is designed as straight through type, which also reduces the flow resistance and head loss.Because the valve stem is sealed with three O-rings and one dust ring, the friction resistance and water leakage can be reduced greatly.

It avoids the lawsuit and claim caused by the theft of manhole cover and the fall of pedestrian. The Best DIN3352 F4 resilient seated gate valve which can be directly buried underground is equipped with a set of protective device. A valve box is set on the top of the device. The cover plate on the valve box can be opened and closed with an extended socket wrench
