Product Description

Q74F Wafer Type Manual Operated T Port Three Way Ball Valve

Product Description

Q74F Wafer three-way ball valve The ball valve opening and closing part (ball) is driven by the valve stem and rotates around the ball valve shaft. It can also be used for fluid regulation and control, among which the V-shaped ball core of the hard-sealed V-shaped ball valve and the metal valve seat of hard alloy surfacing have strong shear force, especially suitable for media containing fibers and micro-solid particles. The multi-port ball valve can not only flexibly control the confluence, diversion and flow direction switching of the medium, but also can close any channel to connect the other two channels. Such valves should normally be installed horizontally in the pipeline. The ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve according to the driving mode.

Product Features

Product features

1. Wear resistance: Since the valve core of the hard-sealed ball valve is spray-welded with alloy steel, and the sealing ring is welded with alloy steel, the hard-sealed ball valve will not wear too much during switching (the hardness coefficient is 65-70).
2. The sealing performance is good; because the sealing of the hard-sealed ball valve is artificially ground, until the valve core and the sealing ring are completely consistent. So his sealing performance is reliable.
3. The switch is light; since the bottom of the sealing ring of the hard-sealed ball valve uses a spring to tightly connect the sealing ring with the valve core, when the external force exceeds the preload of the spring, the switch is very light.
4. Long service life: It has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as people's daily life.

Application

The purpose of the wafer three-way ball valve:

Wafer three-way ball valve is used in the gas pipeline in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the series and connecting valve of the electric demister, the inlet and outlet of the S02 main blower, the adjustment of the converter, the inlet and outlet of the preheater, etc.
Wafer three-way ball valve is used for sulfur incineration, conversion and dry suction in sulfuric acid system. It is the best brand of valves for sulfuric acid plant. It is considered by the majority of users as: good sealing performance, light operation, secondary corrosion, resistance to High temperature, easy to operate, flexible, safe and reliable butterfly valve has been widely used.
Wafer three-way ball valve is widely used in: SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid in chemical, petrochemical, smelting, pharmaceutical, food and other industries , Sulfuric acid, phosphoric acid and other media pipelines are used as adjustment and shut-off devices.

Installation Instructions

How to install and use wafer three-way ball valve

1. Indoor installations or outdoor applications with protective methods;
2. Outdoor open-air installations, eroded by wind, sand, rain, sunlight, etc.;
3. Flammable, explosive gas or dust environment;
4. Wet and dry tropical environments;
5. The temperature of the pipeline medium is as high as 450 ºC or more;
6. The ambient temperature is lower than -20ºC;
7. Easily flooded or soaked;
8. Environment with radioactive substances (nuclear power plants and radioactive substances test equipment);
9. The environment of ships or docks (with salt spray, mold, humidity);
10. Occasions with severe vibration; occasions prone to fire;

Working Principle

How to operate the wafer three-way ball valve

1) Before operation, it must be confirmed that the pipes and valves have been flushed.
2) The operation of the valve drives the rotation of the valve stem according to the input signal of the actuator: when the valve is rotated 1/4 turn (90°) in the forward direction, the valve is closed. The valve opens when reversely rotated 1/4 turn (90°).
3) When the indicator arrow of the actuator is parallel to the pipeline, the valve is in the open state; when the indicator arrow is perpendicular to the pipeline, the valve is closed.
