DIN GLOBE VALVE
The ball valve can be divided into two types: ball type and ballless type. The difference lies in that in ball type, the central hole of the valve core has a sliding V-shaped groove; in balleless type, it does not have such grooves. Both have their advantages and disadvantages.
Product introduction:
The din stop valve is a fast operating spool type with a central spool, which has two or more knee action parts and is operated by hand or motor. The ball is contained in the central hole of the valve core and is fixed by it. The ball type has two tubular bodies, one on each side of the ball, their ends have an internal thread, and a threaded sleeve is screwed into them, so as to form the continuation of the thread on each tubular body and realize the relative movement between them around the common axis.
Din stop valves are simple and reliable, and are suitable for a wide range of general and special pneumatic or mechanical operation applications. They are designed for low and medium pressure and high pressure ranges. It is usually used in large vessels to control and monitor large flows for a long time. DIN stop valves are also used in reactors, compressors or agitators.
Product advantages:
Our DIN stop valves are high quality water management components manufactured to the highest quality standards. With a test pressure of 6 bar and 0.5 MPa, this product is an ideal solution for any application that requires reliable and durable valves. Din stop valves are widely used in industry. Their main functions include guiding or controlling the flow of liquids and gases under pressure, including or excluding solids. The cylindrical valve body integrates flow control through rotating discs and sealing heads connected to both ends of the housing.
Din type stop valve is a new type of parallel displacement stop valve. Its central part is a disc, lying freely on an annular seat ring, which can be rotated by a spherical sealing ball, and the radial and axial distances are equal. The metal body is designed to have the maximum strength, stiffness and fatigue life.
Din globe valves are designed for all applications where large, high temperature and pressure fluids are required to be controlled in the open or closed position. The stop valve has very few moving parts and is usually used in applications that require manual opening and closing of liquid flow, while the standing bypass overflow valve ensures that excess pressure will not be released back to the environment. The stop valve with integral handle can be driven by turning the knob or handle.
Product design:
DIN stop valve is a standard and safety device in industrial environment. It is designed for systems using high-pressure water or steam. Our stop valves have high precision, high reliability and high durability. The carbon steel body of these products ensures corrosion resistance and durability under exposure to hard chemicals, minerals and other harsh conditions. The special design of our products makes them an excellent choice for residential and commercial purposes.
Din globe valves are designed for services that require greater reliability than flared and gate valves. There are four basic types of them. The difference between these types lies not only in the design of the valve body, but also in the details of the trim ring and bonnet.

Advantage
1.Bellow seal element. The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem with automatic roll welding. The metal bellow can keep the stem part no leakage.
2.Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life.
3.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.
4.Grease nipple. It can direct lubricate the stem, nut and sleeve.
5.Ergonomic hand wheel. It provide longer service life and easier operation.
