Product Overview
The ball valve is at home and abroad advanced technology and the development of a new three-way switching type control valve. Standard dual port hole of the L-type three ball core, change the relative angle of the ball core pipeline, different combinations of three pipeline fluid control; T-type channels from the ratio of the role for break fluid, gas, regulation and control of the ratio of steam and other media.
Electric ball valve type HL 3810R type or PSQ rotary rotary electric implementing agencies, AC220V, AC380V or DC24V power supply voltage for the power to accept the input of industrial automation, instrumentation control system (4-20mA or 1-5VDC ) current signal or voltage signal to control operation to achieve regulation, the process medium is the ratio of two to match or two switching control.
Structural characteristics of
A. The ball valve has two and four seal structure, the spool pore structure in the form of L-type and T-control spool rotation angle, change the spool channel and pipe outlet connection status can be achieved on three manifold combination of control. The ball valve flow capacity, to control gases, liquids, steam, more suitable for control of high viscosity, fiber granular fluid. Also applies to the sealing requirements more stringent occasions.
Two. The two-seat sealing ball valve has a compact structure, beautiful appearance, good sealing performance, it can switch to the medium flow in the pipeline. Also make mutually perpendicular two-channel connectivity on or off (such as flow graph A)
3. The four seat sealing ball valve has a beautiful shape, compact and reasonable structure, it can not only switch the flow, but also allows the three channels interconnected, and can turn off any channel, the other two channel connectivity, flexibility and control the pipeline is the confluence or diversion of media (such as the flow of Figure B).
4. T-spool channel allows three orthogonal pipes connected to each other or to switch from the role in the diversion or confluence; L-type channels to connect the two mutually orthogonal pipeline. Another channel cut, starting to change the media flow role.
