Product Description

Pneumatic Globe Control Valve is a reliable flow regulation solution designed for industrial automation systems requiring accurate control and stable operation. With pneumatic actuator technology and precise valve structure, it enables efficient adjustment of fluid flow, pressure, and process conditions.

Designed for demanding industrial applications, the pneumatic globe control valve provides excellent control accuracy, fast response, and dependable performance. It is widely used in chemical processing, power generation, oil and gas, water treatment, and other industrial systems.

With durable construction, flexible automation capability, and reliable sealing performance, this valve helps customers improve process efficiency, reduce manual operation requirements, and achieve safer and more stable industrial control.

Outline
The 50F Series soft seal floating ball valve has simple structure. The ball adopts the floating structure. The single-way force acted by the medium on the ball makes the ball move closer to one side of the PTFE seat. The sealing function is realized through extruding the seat. It is mainly used for shut-off applications in low pressure service conditions.
The 50F 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.

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: DN15 – 200
Pressure rating: 150LB – 300LB,PN1.0 – 4.0Mpa
Connection type: flange 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 50F Series softseal floating ball valve

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. It is protected by the upper protruded platform on the body to ensure that the stem will not be blown out under any pressure and play the function of back seal (figure 1).
Antistatic device
The antistatic device is a standard design of REOWO floating 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. The static electricity accumulation is very dangerous in some service conditions (figure 2).
Fire safe design
When the nonmetal seals are damaged or decomposed by high temperature in case of fire, the ball is pushed by the pressure to contact the metal lip seat and realize metal-to-metal sealing so as to shut off the fluids and minimize internal leakage.
In addition, the fire safe metal seat can prevent the erosion of the soft seal seat by the medium pressure and reduce creep deformation of the soft seal seat. All floating ball valves are designed to be fire safe and are tested and certified in accordance with API 607.
