Q:What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?: Force code valve industry for you to resolve their differences:Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight.Butterfly plate driven by the stem, if you turn 90 degrees, you can complete a headstock. Change the deflection angle of the butterfly plate to control the flow of the medium.Sealing performance of the ball valve is better than butterfly valve.

Q:Hard sealing ball valve, what method can calculate the leakage? How much is grade 4? How much is grade 5? How much is level 6? For example: how many DN150 seals are 5 ml?: Valve leakage level is actually the valve sealing class. There are two kinds of GB and American Standard.

Q:The working principle of the track type ball valve: No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.

Q:What is the ball valve Q11F -16 material?: If sealed, F stands for fluoroplastic. Valve material is not marked in the model!Q stands for ball valvesThe first 1: threaded connection,Second 1: is the ball valve is floating through the ball,F stands for PTFE- PTFE seals16 represents the nominal pressure of the ball valve is 1.6MPa=16 kg

Q:Into the tap valve, with globe valve or ball valve?: Just don't buy cheap goods, cheap ball valves use a period of time, gland leakage, spool corrosion must be replaced.

Q:Why is there a water or oil in the new ball valve?: Forged steel ball valve installation will add butter to prevent damage to the seal, test pressure, if you use the water test pressure, generally will remain some of the normal

Q:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?: So you must first determine the pressure level of your ball valve, and then determine the valve flange used standards, and then you can determine the basic parameters of the ball valve flange.

Q:DN15 ball valve with a bit of outer wire: Outside the wire of 1/2, which is DN15, the wire wire twisted together just bite

Q:The difference between gate valve, ball valve and butterfly valve: Gate valve: there is a flat plate in the valve body which is perpendicular to the direction of the medium flow, and the plate is lifted and closed.Features: good tightness, fluid resistance small, open and close force is small, widely used, also have to regulate the flow performance, generally applicable to the large diameter of the road.Ball valve: the use of a hole in the middle opening of the ball as the spool, by rotating the ball to control the opening and closing of the hair.Features: the structure is simpler than the gate valve, small size, low fluid resistance, and can replace the role of gate valve.Butterfly valve: closure is a disk-shaped, around a fixed axis rotation of the valve body.The utility model has the advantages of simple structure, small size and light weight, and is suitable for making larger diameter valves. As the sealing structure and materials are still problems, it is only used for low pressure, for the transport of water, air, gas and other media!Own code words, hope to adopt!
