V Type Ball Valves:

1.        Application:

V notch ball valve is quarter turn control valve mainly recommended for throttle service, but it is also applicable for switch valve. V type ball is in V-notch design with strong custting force and self-cleanness, especially suitable for control of medium containing fibre and tiny solids. Therefore, it is widely sued in the self-control systems in industries such as paper, petrochemistry, petroleum, checmial fibre, power, metallurgy, pharmacy, environmental protection, etc.

2. Spring Loaded Valve Seat:

Pre-tightened loaded seat keeps valve seat and ball in constant close contact, therefore, good sealing performance is assured even at a long differential pressure with greatly extended service life. PTFE soft seat and metal seat are available for different media and temperature.

3.        One-piece Valve Body

One-pcs valve body prevents potential leakage patch caused by flange connection.

4.        V-notch Ball and Automatic Sliding Bearings:

Specially designed V-notch ball provides equal percentage flow characteristic with high prescision control performance as well as strong cutting force and self-cleaning function. Upper and lower shaft are fixed by double bearings with good stability. Bearing s are in composite material, and loaded surfaces are sintered with superior abrasion resistant and self-lubricating function, which prevents valve seizing up during service life.

5.        Spline Connection Between Shaft and Ball

Ball and shaft are connected by spline, which keeps good neutral position with large load bearing capacity and long service life. It also eliminates the room between the stem and ball, and the dead band phenomenon is prevented with enhanced control precision.

6.        Low Capacity

For customers’ flow applications, low capacity vales are available with DN25 for precise control. Non-standard flanges are needed for connection with DN20 and DN15 pipe.
