Product Description

Outline
The 50GR Series soft seal trunnion ball valve is a high performance soft seal ball valve developed by our company through digesting and absorbing the latest international technologies on the basis of many years of ball valve design and manufacturing experience, suitable for chemical industry, petrochemical industry, anticorrosive application and other service conditions.
The 50G Series valve is an ideal product used for on–off in the pipes. Featured by compact structure, light weight, high flowing capacity, strong shut–off performance, long service life, etc., it is the best choice in steam, hydrocarbon, corrosive media and other service conditions. It has prominent performances especially in chemical industry, air separation, water supply system, etc. It is an ideal choice of users.
Actuator and auxiliary control device

Pneumatic
Electric
Pneumatic–hydraulic

Applications

Chemical industry and air separation equipment
Coal liquefaction or coal gasification
Hydrocarbon
Power plant
Water supply and heat supply systems

Manufacturing range

Size range: DN2" – 40"
Pressure rating: 150LB – 900LB，PN1.0 – 15.0Mpa
Connection type: flange type,butt welding type

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 50GRSeries softseal trunnion ball Valve

Design features

Blow-out proof stem
The stem and ball are separate. One end of the stem that is near to the ball is designed into the integral T type structure. The gland flange can block the T-shaped stem to prevent it from being blown out by cavity pressure.
Antistatic device
The antistatic device is a standard design of REOWO ball valves. The stem is installed with the spring grounding plunger to maintain continuous contact between the ball, stem and body and form a conduction circuit to transfer the electric charge, avoiding static electricity accumulation produced due to friction during the valve opening and closing or due to fluid impact on body cavity. The static electricity accumulation is very dangerous for the pipelines in some service conditions.
Super fire safe design
External leakage prevention:
Under normal conditions, leakage from the stem area is prevented with the design of two O rings and a graphite gasket. Leakage at the places that connect the body with bonnet is also prevented by an O ring and a body graphite gasket. After the O rings are damaged in case of fire, the gland graphite gasket, body graphite gasket and stem graphite packing will prevent external leakage of the fluids.
Internal leakage prevention:
When the nonmetal seals such as O ring, soft seal seat and seat ring are decomposed by fire, the metal seat lip will be pushed by the pre-tightening force of the spring to contact the ball, shut off the fluids in the pipeline, minimizing internal leakage in the valve channel. In addition, the flexible graphite seat packing is compressed by the seat spring to prevent leakage of the fluids between the body and seat.

Emergency sealant injection system
For 6 inch (DN150) and larger REOWO trunnion ball valves, the sealant injection fittings will be installed on the stem and seats. When the sealing materials (seat seal ring or O ring) are damaged or decomposed by fire or other accidents, the stem and seat leakage can be prevented by the injection of sealant into these fittings. The fitting is provided with a check valve to provide backup sealing and prevent backflow
Double block and bleed
The two seats of the trunnion ball valve can shut off the fluids from the upstream and downstream sides, realizing the double block function. When the ball is fully opened or fully closed, even the pressure is simultaneously applied to both sides of the valve, the valve cavity and channel are isolated from each other, and the residual medium in the cavity can be discharged by the bleed valve.

Structural features of 50GR Series softseal trunnion ball valve

Cavity pressure relief
When the cavity pressure (Pc) is lower than seat spring pressure (Fs) and pipeline pressure (P1), i.e., △PXD1 < Fs, the ball and seat are in close contact with each other to ensure sealing.
When the cavity pressure (Pc) is higher than seat spring pressure (Fs) and pipeline pressure (P1), i.e., △PXD1 > Fs, the cavity pressure will slightly push the seat away to produce a small interval between the seat and the ball. Therefore, the excess pressure in the cavity will be automatically discharged into the pipeline, and the pressure balance between the cavity and pipeline (upstream or downstream side) is restored.
Self relieving seats (single piston effect)
The pressure of fluids at the upstream and downstream sides pushes the seat toward the ball.
If the cavity pressure produced by the medium is higher than the spring pre-tightening force and the fluid pressure, the seat will be pushed by the cavity pressure to leave the ball. Any excess pressure produced in the cavity will be automatically discharged when the valve is fully opened or fully closed.
Double piston effect seats
The upstream and downstream pressure creates thrust to always push the seat toward the ball and maintain the status of sealing. The double piston effect ball valve does not have the cavity self relief function. Therefore, it is generally required that the valve should be installed with the automatic pressure relief valve on its body so that when the cavity pressure is too high, the pressure will be discharged by the automatic pressure relief valve.
