Q: Check valve H41T-16. What are the numbers and letters in it?: H stands for check valves, 4 for flanges, 1 for lift, T for seal, and 16 for pressure

Q: Detailed distinction between backflow preventer and check valve: The backflow preventer consists of two separated check valves and a drain valve. Due to the local head loss of the check valve, the pressure in the middle cavity is always lower than the pressure at the inlet. This pressure difference causes the drain valve to be closed and the pipe is in normal water supply. In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.Check valves are plain check valves, only one side seal. Backflow preventer is more expensive than ordinary check valve. Double protection and heavy protection!

Q: Check valve h42h-dn80 what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve4 = connection: flange2 = structure form: vertical lifting typeH = sealing surface material: Cr13 stainless steelDN80== nominal diameter: 80mm

Q: What is the check valve?: Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class.The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.

Q: What is the difference between the check valve rcvx and SFCV?: SFCV rubber check valve parts design mainly by the body, valve cover and rubber valve composed of three major parts. Its main features are: rubber valve in the valve by the steel plate, steel bar and reinforced nylon cloth as the substrate, the outer rubber covered, the valve switch life of up to 1 million times. H44X (SFCV) series rubber check valves adopt full flow area design. They have the characteristics of small head loss, easy accumulation of debris, easy maintenance and so on. H44X (SFCV) series rubber check valve is mainly suitable for horizontal installation of water supply and drainage system. It can be installed at the water outlet of the pump to prevent backflow and water hammer damaging the pump. H44X (SFCV) series rubber check valves can also be installed on the bypass pipe of the reservoir inlet and outlet to prevent backflow of water to the water supply system. Check valves are generally applicable to clean media and are not suitable for media containing solids and viscosity.Analysis of the main characteristics of RCVX rubber valve check valve: the valve body, valve cover, valve and spring, mainly used for pipeline industry departments of water supply and drainage system, oil and chemical exports, to prevent the media counter. Due to the design of the sealing ring of the product, the closing time is short, and the water hammer pressure can be reduced. The valve is made of nitrile rubber and steel plate by high temperature. It is resistant to erosion and has good sealing performance. The product structure is simple, and the maintenance, maintenance and transportation are very convenient.

Q: Is the check valve and relief valve something?: Not the same thing!!! Installed on the water heater will not have too much money, less than 10 should be enough, but most of the water heaters are non - targets, may not be too good to match, you'd better go to a larger plumbing market

Q: What does the check valve h44t-16 mean?: Flanged swing check valve [H stands for check valve, 4 represents flange, 4 represents structural form (swing type), T represents internal copper alloy, and 16 represents pressure 16 pressure. I hope it will help you

Q: What are the main types of check valves?: Check valve structure of the main drop type, DL swing and butterfly, JB/T308 provides the structure code.

Q: I have to use a check valve to prevent return water due to pipe installation problems due to regular water supply. But the recent discovery of a running water phenomenon, just on a full tank of water slowly from the pipeline flow away, but not all go, a flow did not flow, time is not the same, but sometimes sometimes does not flow, this is going on, ask professional personage answer: You should be horizontal check valve, with pressure difference, water pressure is not lost; or a check valve inside where the card, must be a certain pressure to baffle back.

Q: How can the fast closing noise check valve prevent water hammer?: Quick closing silencing check valve prevents water hammer principle:Once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, reduce the amount of return equal to the reduction of gravity. Fall short height reduces the inertia time is also relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.Quick closing and silencing check valve and silencing check valve is to rely on the flow of the medium itself automatically open and close the valve, backflow valve to prevent the media, also known as check valve, check valve, silent check valve reflux valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).

We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on). Our products are widely used in municipal water and wastewater ,oil,chemical, food and other fields.Our entire valves are designed and manufactured according to ANSI (ASME), DIN, BS, JIS and other standard. Also, we ensure the best quality for customers, and our strict quality assurances systems are conducted throughout the entire production at the standard of ISO9001:2008 and CE.
