4104 Series Eccentric V-Shape Ball valve

4104 Series eccentric butterfly valve and seal ring using a unique

eccentric structure, with a compact structure, good sealing

performance, long service life and so on, with both functions of

regulating and cutting off. Widely used in chemical, electric power,

textile, food, medicine, paper and other industries on the process

medium for cutoff or regulation control.

The use performance of this product leading domestic, up to the

international advanced level!

The nominal pressure level of this series of products are :

ANSI150Lb, ANSI300Lb, PN (MPa) 1.6. 4.0. 6.4; service

temperature -60 ~ 450 ℃; metal sealing type sealing Class V, soft

seal type is Class V, and even up to zero leakage; flow

characteristics are approximate equal percentage.

Characteristics

· Valve body adopts whole casting technology, compact

structure, small volume, good pressure resistance;

· V-shape ball core eccentric mounting. When closing, the

ball core generates an eccentric force, which causes the

ball core to press against the seal ring to achieve the best

sealing effect; when opening, the ball core and the seal ring

are quickly disengaged, which effectively prevents the seal

ring from wearing out; There are two types of seal

rings for selection, soft seal and metal hard seal, to meet

the requirements of different working conditions, the sealing

surfaces are made of build-up welding Steillet alloy and

can be used for some of the more demanding working

conditions;

· Due to the usage of eccentric structure, the operating

torque is greatly reduced and the allowable differential

pressure of the valve is increased;

· The surface of ball core is hardened, smooth and wearresistant after grinding, and the sealing surface can be build

-up welded with Steillet alloy;

· Simple flow paths, high flow capacity and adjustable

ratios of up to 100;

· V-shape ball core and seal ring have a shearing effect at

the moment of closure, it can cut off fiber and extrusion of

particulate matter in the medium, especially for pulp,

sewage and other media containing fiber, particulate matter

, and also for general media;

· Standard actuator (pneumatic piston, electric) are

interchangeable. Pneumatic Eccentric V-Shape Ball Valve

Pneumatic piston actuator adopts double-piston rack

and pinion mechanism, which has the advantages of

small structure, large output force, accurate action, and

strong interchangeability between single-action and

double-action.

Reasonable design for eccentricity E, when closing,

the ball core generates an eccentric force, which

causes the ball core to press against the seal ring to

achieve the best sealing effect; when opening, the ball

core and the seal ring are quickly disengaged, which

effectively prevents the seal ring from wearing out;
