Advantages of the ball valve:

v notch ball valve

1, has the lowest flow resistance;


2, can achieve complete sealing within a larger pressure and temperature range;


  1. Quick opening and closing can be realized. When opening and closing the valve quickly, there is no impact on operation;


  1. The working medium is sealed reliably on both sides;


  1. When fully open and fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface;


  1. Compact structure and light weight, it can be considered as the most reasonable valve structure for low temperature medium system;


  1. The valve body is symmetrical, especially the welded valve body structure, which can well withstand the stress from the pipeline;


  1. Fully welded ball valve can be directly buried in the ground, so that the valve's internal parts are not eroded, and the maximum service life is up to 30 years.


As a professional V-notch ball valve manufacturer, we guarantee product quality and delivery time, and we have perfect after-sales service.


Product Overview

VN6 series V-ball valve is an angular stroke control valve with V-shaped opening on the spool, which has a strong shearing effect on the sealed seat during the spool rotation, in addition to the valve has a large adjustment ratio. Especially suitable for control systems requiring large adjustment ratios and control of fluids containing fibers and slurries. So far, more than 2000 sets of applications have been achieved in the paper, food, chemical, fine chemical and other industries.


Performance advantages

Spool and stem spline connection, good alignment and stability, small torque loss, avoid dead zone, high adjustment accuracy.


Double bearing fixed upper and lower valve stem, good self-lubrication, stable spool operation, valve action is not easy to bite.


The valve seat adopts waveform spring preload, self-compensating seal, good sealing performance, modular design, adapt to high and low temperature online replacement.


The valve seat adopts elongated design, the flow path of the upper cavity of the valve body is fully protected from scouring, which improves the service life of the valve.


Soft seal vice elastic compensation floating type design, relying on medium pressure to improve the sealing specific pressure, reliable sealing.


Easy installation and disassembly, easy maintenance.


Seat leakage: hard seal V-shaped ball valve conforms to ANSI B16.104 Class V; soft seal V-shaped ball valve conforms to ANSI B16.104 Class VI.

About The Company


Specialized in foundry technologies and solutions for worldwide manufacturers of pump, valve, electric motor, compressors, etc. We supply various castings and mechanical parts for various industries.


Zen Young's foundries implement investment casting,sand casting,and lost foam casting processing.


The investment casting foundry covers an area of around 30000m2 with 110 employees. Following the standardized production of ISO 9001:2015,we can handel material in stainless steel, bronze, aluminium,carbon steel, low alloy steel, non ferrous alloys,like 304,316 Stainless steel, CD4MCu,CA6NM,SS420,etc.

Our products serve the industries like OEM Pump Volute, automobile, food, chemical, pharmacy, airplane and aerospace and so on.

The sand casting foundry occupis over 130.000 m2, facilitated with a resin-sand processing line, a disa line and a 5 tons electric furnace, CNC lathes, CNC milling machines, CNC boring machines, CNC machining centers, heavy- duty lathes, vertical lathes, vertical drilling machines, etc.The foundry is able to cast parts weight from 0.1kgs up to 10,000kgs, to machine size up to 1600mm( rotating diameter). Annual output exceeds 10000 tons including all kinds of material like grey iron GG15, GG20, GG25, GG30, ductile iron GGG400-18, GGG500-7, GGG600-3, and GGG700-2, high-Chrome cast iron KmTBCr26, high-nickle casting iron D-5S, and also Austempered Nodular Iron. We can also supply wear-resistant alloy, like high manganese cast steel, for oil,mining and metallurgy industries. These high quality alloy parts provide our customers with longer wear life and improved efficiency.


With strict quality control system, and top chemical and metallurgical laboratory facilities, like spectrometer, ultrasonic detector, universal material tester, metallographic analyzer and CMM, we can ensure the exact material quality and standard as well as mechanical properties.


Our aim is to realize further studies of modernization and to be a "brand" in the international market with  "Quality", "Reliability", "Zero defect policy" and "on time deivery" strategy.


Sincerely welcome your visit and cooperation!
