Product Details

NSV Three-way trunnion mounted ball valve have two types: T and L shape, it is used for switching, converging and diverging pipeline medium flow direction .T - shape can make three orthogonal pipelines connected with each other and cut off the third channel, play the role of shunt, confluence Three-way ball valve type can only connect two mutually orthogonal pipelines, and cannot maintain the mutual connection of the third pipeline at the same time. It only plays a distribution role.

It is widely applied in metallurgy, mine, petroleum, chemical industry, electric power, light industry, shipping industry and automation control systems, suitable for service conditions such as switching, mixing and diverging of fluid, gas and power.

1.STRUCTURAL FEATURES

The three-way/four-way ball valve is provided with reliable sealing and smooth flow channel so as to ensure accuracy of opening and closing through small fluid pressure loss and stable flow channel. According to the forms of flow channel, the valve can be classified into "Y" pattern three-way ball valve, "L" pattern three-way ball valve, "T" pattern three-way ball valve and "LL" pattern four-way ball valve.

"Y" pattern Three-way Ball Valve(Q42 Type)
The form of flow channel is "Y" pattern, which can effectively realize switching from service condition 1 to service condition 2. It is mainly used for switching "Y" pattern pipeline flow direction.

"L" Pattern Three-way Ball Valve(Q44 Floating Type,Q49 Trunnion Type)
The "L" pattern three-way ball valve is used for switching pipeline medium flow direction. It can connect two flow channels that are vertical with each other. The ordinary "L" pattern floating three-way ball valve may not be suitable for some service conditions, which shall be paid special attention to when users select it.

2.STRUCTURAL FEATURES
"T" Pattern Three-way Ball Valve(Q45 Floating Type,Q48 Trunnion Type)
The "T" pattern three-way ball valve is used for switching, converging and diverging medium flow direction. The "T" pattern ball channel can make three channels connect with each other or two of them connect with each other to realize two, three of found kinds of functions. Different valve designs are adopted to realize different functions. Therefore, users shall make detailed descriptions to the service requirements when selecting and ordering the "T" pattern three-way ball valve, so that our company can make designs and configurations correctly. The ordinary "T" pattern floating three-way ball valve may not be suitable for some service conditions, which shall be paid special attention to when users select it.

3.Advantage

1.The fluid resistance is small, and its resistance coefficient is equal to the same length of pipe section.

2.Simple structure, small size and light weight.

3.Close reliable, good sealing, in the vacuum system has been widely used.

4.Easy to operate, fast to open and close, from full open to full close as long as the rotation of 90°, easy to remote control.

5.Easy maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.

6.When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, which will not cause erosion of the sealing surface of the valve when the medium passes through.

7.Wide range of applications, from small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.

FAQ

1. Q: What’s the valves warranty?
A: Our valves warranty period should be 18 months from the date of shipment or 12 months after installation, whichever occurs first.

2. Q:Does “NSV” valves have supply to any value end user?

A:Yes,it just like PETROKIMIA GRESIK in Indonesia, BP Iraq,ESFAHAN MOBARAKEH STEEL In Iran etc.

3. Q:Are you manufacturer or trading company?

A: We’re manufacturer,but our factory name is not named NSV due to we’re professional in promotion NSV brand with best service,and also have sold to many end user success.
