Valves suitable for lines with abrasive fluids,
highly viscous fluids, etc.
Excellent performance in heat resistance,
wear resistance, and flow control.
Ball of the V-port valve
Since the opening side of the hemispherical ball is cut into a V-shape, it has the effect of cutting fiber and solid matter.
Stellite is also applied to the sealing surface of the ball, and it is lapped, so it has excellent abrasion resistance (hard chrome plating is applied for the soft seat).
The valve seat exists at primary surface only, so fluid will not accumulate in the valve flow path or become clogged between the ball and the body.
Also, this primary side seal structure does not cause abnormal pressure rise.(There exist restrictions on the flow direction. Details are here.)
The seat combines rigidity and flexibility to seal from vacuum to high pressure due to the effect of temperature and pressure difference. Metal seats allow use up to high temperatures.
It is also wear-resistant against abrasive fluids such as slurry and powder.
Specially reinforced PTFE is used for the radial bearings of the stem and trunnion. Therefore, the operating torque is low and it can withstand high frequency operation.
V-packing provides complete sealing from vacuum to high pressure (V100ND type).
Since the valve body is integrated, there is no fluctuation of valve torque due to piping stress, deterioration of sealing performance, or external leakage.
When the valve is fully open, the valve body is almost straight without obstructing the flow, so the pressure loss is small. In addition, it is possible to smoothly pass slurry, etc., which makes it difficult to cause fluid clogging and cavitation.
Since the ball is V-cut, the rangeability is high and the flow rate control performance is excellent.
The specific flow characteristics are nearly equal percent.
