Q: How much pressure can the flange ball valve withstand?: How many can, each kind of pressure specification has the different material quality, the thickness request, the ball valve can also use in the high pressure class.

Q: For our valve beginners, how intuitive decision is floating ball valve or fixed ball valve?: Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve

Q: What does the sealing surface of the ball valve stand for HF?: HF= hard solder material in valves Q347HF, -16C, welded with CoCr or NiCr alloy.

Q: Switch valve type, switch valve, ball valve or butterfly valve is good: Ball valve and butterfly valveBall valve is used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.Butterfly valve, also known as shutter valve, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. On the pipeline, mainly from cutting and throttling.

Q: What does "2P" ball valve mean?: 2P is made up of two parts. The price of 2P is higher than that of 1P, and its performance is good.

Q: How to distinguish between single and double ball valve?: Single ball valve, pneumatic ball valve is a single short; double valve, double acting pneumatic ball valve is referred to as.Single acting pneumatic ball valve is open air, spring off; and double acting pneumatic ball valve, gas gas is closed.Single / double ball valve, is divided according to the actuator, the actuator has a single pneumatic actuator and double acting pneumatic actuator.Single acting pneumatic actuator Pneumatic actuator to more than double spring, loss of gas supply, the spring to reset actuator.For hazardous media or conditions requiring a safe position when the gas source is lost, a single action is recommended.Selection must be based on the size of the field air pressure to select the spring force, otherwise it may cause air pressure is less than overcome the spring force and can not drive the actuator.When the actuator is selected, the minimum spring force should be allowed to drive the valve normally, taking into account the gradual reduction of the spring force.

Q: What's the meaning of the ball valve bore 14 "x 12"?: The inner diameter of the two ends of the ball valve is 14 inches at one end and 12 inches at the other.

Q: Where can I buy this Y filter with a ball valve?: This valve is added after the filter, directly on the flange welding joints or holes in the flange is connected with a ball valve tapping, can double wire, because the Y type filter is standard, relatively good buy, relatively less modification

Q: What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?: In general, both sides of the ball are wire interface, and hot melt ball valve on either side or side of the live connection with PP-R short tube, as a hot melt interface, so called hot melt ball valve. As for the use, there is no obvious difference, but the connection is different.

Q: Structure design principle of fire ball valve: The fire ball is fixed ball structure, the upper end of the main seal seal, the seal has the function of DBB, in good condition, the valve in the fully open or fully closed state, the cavity in the outfall or vent to observe the upstream seat leaks. Pipeline ball valve in normal use, the middle chamber without pressure. In the case of fire accidents, a reasonable design of the fire protection structure of the valve seat can slow down the progress of the upstream pressure medium into the middle cavity, and avoid the leakage and leakage of the medium caused by the boosting of the middle cavity. The valve seat with good fire protection design is an active measure to ensure the safety and fire resistance of the pipeline ball valve.The fireproof structure design, the design of the seat structure fire is the key, the seat of the fire performance is good, in the fire accident condition, fire structure design of the pressure between the body and the stem structure, reduce the fire around the body.
