Product Description

Outline
In the 50GY Series hard seal trunnion ball valve, the seat surface is subjected to hardening treatment, the ball is coated with tungsten carbide and the sealing seat is loaded by the spring. It has excellent sealing performance under a wide varieties of pressures and temperatures, ensuring stable running under high temperature and high pressure service conditions. The optimized stem design makes the whole valve maintain the lowest operating torque. The 50GY Series valve is mainly used in severe service conditions such as high temperature, high pressure, strong corrosion and other service conditions with media containing granules. Due to its advantages, the hard seal ball valve is widely applied and receives more and more favor from customers.

Stem sealing

The graphite packing formed through mold pressure serves as the dynamic load seal to ensure reliable sealing and long service life.
The high strength stem can effectively transfer torque and ensure reliable on–off of the valve.
The stem and ball fit tightly with each other, reducing hysteresis and dead band with excellent control performance.

Seat sealing

The seal conforms to the requirements in GB/T13927 Class D or ANSI/FCI70–2 CLASS VI.
Reliable double–way sealing
Excellent sealing performance in low pressure service conditions

Structural features of 50GYSeries hardseal trunnion ball Valve

Blow–out proof stem
The bottom end of the stem adopts the integral T type structure, which is a blow–out proof design. The side entry type stem structure is inserted into the body to ensure stem safety under any pressure. In addition, it also has the function of back seal to further ensure reliable sealing.
Fire safe and antistatic design
The fire safe and antistatic design is a standard design of REOWO ball valves. The seal assembly (seat, body, spacer, packing, etc.) of REOWO metal hard seal ball valves is made of metal or graphite of excellent fire safe performance to realize fire safety. Continuous metal contact between the ball, stem and body is maintained and a conduction circuit is formed to transfer the electric charge and avoid static electricity accumulation produced due to friction during the valve opening and closing or due to fluid impact on body cavity.

Low leakage packing design(suitable for the graphite packing structure metal hard seal ball valve)

The metal hard seal ball valve is often used in severe service condition. To ensure the overall sealing performance of the valve, the graphite packing structure metal hard seal ball valve adopts low leakage packing. The packing is composed of parallel layers and tapered seal layers. It is a flexible graphite assembly with such performances as high temperature resistance, low stress release, low creep deformation, etc. With these performances, the friction produced when the stem turns is effectively reduced and stable sealing performance at the stem under long running conditions is ensured.
Various types of seat structures
① The elastic seat with automatic compensation function is adopted. The sealing face is hard alloy to ensure reliable sealing, high temperature resistance, wear resistance, corrosion resistance and long service life. Due to the features of the metal sealing face, fire safe performance can be realized in a real sense. It is applicable to high temperature (−50℃ – 400℃) and granules service conditions.
② In severe service conditions with media containing granules, the solid small granules and dust will enter the spring structure, influencing normal work of the pre-tightening spring. REOWO metal hard seal provides the optional seat structure to effectively prevent solid granules from entering the spring hole and influencing the pre-tightening function of the spring, so as to enable the ball and seat to achieve good shearing and self-cleaning functions. It is suitable for controlling media containing granules and fibers.
③ In some chemical industries, the conventional soft seal trunnion ball valve cannot meet the requirements of the highly corrosive media, and it is required to enhance the sealing performance and sealing class to the utmost extent. REOWO has developed the metal hard seal ball valve suitable for normal temperature & middle temperature (−50℃ – 250℃). The metal-to-metal sealing method is adopted between the ball and seat, and O ring sealing structure is adopted at the packing and seat, so as to effectively enhance overall sealing performance of the valve and reduce the torque.
