Soft Sealed Gate Valve Manufacture in China
The valve plate of the soft sealed gate valve adopts a precision casting process. The valve plate is made of nitrile rubber (NBR) sintered, isolated from the medium, and there is no corrosion phenomenon. Nitrile rubber has excellent wear resistance and corrosion resistance, high elasticity, and long service life in a natural gas medium environment.
Due to the use of the rubber sealing principle, the soft sealing gate valve is very suitable for various gas media; Even if there are rust and impurity particles in your pipeline, the valve plate will only be slightly scratched, which will not cause internal leakage, and the sealing life without maintenance can last for more than 30 years.

Elastic Soft Seal of Soft Sealed Gate Valve
The rubber-sealed buried valve body of the soft seal gate valve you are using is made by precision casting technology, which has a beautiful appearance and no defects such as air holes and welds. The valve body channel is a full-diameter structure, and the opening and closing part is the gate plate; The flap is a concealed rod, which can move vertically up and down along the axial channel of the valve body. The main sealing component of this maintenance-free manual bottomless buried gate valve is the NBR nitrile rubber-coated integrated gate plate, which will produce a small adaptive elastic deformation under the action of working force and medium pressure, and form a good sealing effect with the precision cast valve seat.
Liangzheng as Your Partner
The company applies the advanced management concept to the factory management mode, which is perfectly combined with the UKAS-ISO international quality assurance system and the on-site 6S standardized management. From the selection of raw materials to the finished product leaving the factory, the advanced MES intelligent manufacturing management system (LMES) is used throughout the process to manage product flow and quality traceability, achieving professional, automated, standardized, and procedural organization of production.
Application Scenarios of Soft Sealed Gate Valve
When we close the soft sealed gate valve, the valve seat will be released from the locking state to prevent the valve from sticking.
The NBR nitrile rubber soft sealing material in our soft sealed gate valve has corrosion resistance and anti-corrosion performance, high elasticity, and long service life in natural gas medium environment.
The valve body surface of our soft-sealed gate valve is coated with ultra-thick epoxy resin powder by the electrostatic spraying process, which has excellent adhesion, wear resistance, and corrosion resistance.

Customer's Evaluation of Soft Sealed Gate Valve
Our municipal water company purchased your company’s soft sealed gate valve for the water supply system renovation, and the effect after half a year of operation far exceeded expectations. The valve has excellent sealing performance, completely solves the problem of pipeline leakage, has small operating torque, and is easy to maintain. The supplier also provided detailed operation training and remote technical support, and responded quickly. I strongly recommend it to my colleagues who need an efficient water solution!
Senior EngineerUnited StatesAs the equipment manager of the sewage treatment plant, I have extremely high requirements for the corrosion resistance and stability of valves. Your company’s soft sealed gate valve performs excellently in sewage pipelines, with EPDM sealing material effectively resisting corrosion and smooth operation without jamming. The packaging is professional, the delivery cycle is short, and the cost-effectiveness far exceeds that of similar products in Europe. It has been planned to expand the scope of procurement.
Equipment ManagerBrazilThe construction project has a tight schedule, and your company’s soft sealed gate valve has a fast delivery speed, easy installation, and saves a lot of time and cost. The valve seal is reliable, suitable for a variety of pipe diameters, and the quality is comparable to imported brands, but the price is better. A very trustworthy supplier!

The valve body and valve cover of our soft sealed gate valve are made of precision castings. All are precision cast in one piece, with a beautiful appearance, no pores, welding defects, PE welding and steel sleeve welding gate valve valve body and valve cover material is WCB, flange connection gate valve valve body and the valve cover material is QT500-7, high strength and corrosion resistance. The valve seat and valve body are precision cast together with silicon colloid, and no processing is needed.
The valve body sealing surface of the Liangzheng soft sealed gate valve is an S-shaped precision sealing curve, not a slope or a plane. The S-shaped curved seal is more in line with the gap between the gate plate, making the gap between the gate and the valve body very small, and the delicate fit makes it difficult for fine particles and impurities to enter the valve cavity. When the gate is fully opened, the bottom of the gate valve is flat, and the impurities will not accumulate in the valve cavity. The reliable upper seal makes it impossible for the impurities in the pipeline to enter the valve cavity, preventing the accumulation of impurities and internal leakage.
Low torque of soft sealed gate valve.
When the valve is fully open, the flap is completely detached from the flow channel, and the valve body channel is equivalent to a full-diameter structure and a straight pipe.
The Gate Nut of the Soft Sealed Gate Valve, Etc.
The nut of our soft sealed gate valve is fixed on the gate plate, and it is connected with the gate plate as a whole by means of a threaded connection and a screw stop at the seam, with no movement and no loosening. Aluminum bronze (Z) CuAl10Fe3 material, self-lubricating with the valve stem, effectively reducing the operating torque.
Our soft sealed gate valve has a non-grooved flat bottom flow channel that does not accumulate impurities, no need to remove impurities, the bottom of the flow channel is non-grooved and does not accumulate impurities. The valve body design with no groove at the bottom of the flow channel, which does not require slag removal and maintenance, can effectively save installation height space compared with other structures of gate valves, such as flat gate valves and wedge gate valves, and can also greatly avoid the leakage of the valve due to the influence of bottom impurities on the sealing.
