Electric V-type adjustable ball valve ,match with HL series electric actuator ,without reprovision servo amplifier and can be run with input (4-20mA.DC, 0-10VDC or 1-5V) single-phase power .To realize the regulation of pressure ,flow ,temperature ,liquid level and other parameters. The V-cut is opened on the spool ,and the shear force is generated by the comparative rotation with the hard seal valve seat .which can make the fiber cut off ,preventing stuck .With flow capacity ,high regulation precision ,good sealing ,and light weight ,etc .Apply to majority of pccasions ,except the small diameter ,angle ,and the triangle connecting .Particularly suitable for the regulation of the mud and fibrous medium ,and small suspended solid media .Widely used in papermanufacturing ,sugar ,petroleum ,chemical ,metallurgical and other industrial automation control systems.
1. The introduction of German technology with simple Design Structure ,light weight ,low material cost ,more cheaper than thelinearmotion valve of the same flow capacity .
2. Without any connection with the overall style body ,therefore not subject to a pipe or bolt stress ,and because no pipe fittings of the valve body, so that the pressure hull is not affected by pressure "mutation".
3. There is stainless steel inner core ,PTFE cup or O-ring in the outer diameter of leakproof and durable seat .The valve seat is made of tungsten carbide cobalt ,the structure of the valve seat is further strengthened by a alloy wave spring.
4 .The V -type valve can ensure the accuracy of control even in low flow or high viscosity media case ,and also within the entrie range.ºC
5. When the valve is closed ,The Wedge shearing action is created between the V-notch and the valve seat ,and both have self-cleaning function and also prevent the ball core stuck ,especially for frozenpipes ,the fluid containing fiber ,slurry type fluids ,high viscosity fluids ,including polymers ,particles ,crystal and other flow control situations.
