A manual V-type ball valve is a rotary ball valve with a metal core and seat, or a metal-to-PTFE sealing fit. It combines the control characteristics of a ball valve and a butterfly valve into one, and can be used as a control and regulating valve or a shut-off valve. Its main features are:
(1) An integral valve body without any pipe fittings, thus unaffected by pipe or bolt stress, and because the valve body has no pipe fittings, the pressure-resistant shell is not affected by sudden pressure changes;
(2) It has a V-shaped valve body, ensuring accurate control throughout the entire flow range, even with low flow rates or high viscosity media;
(3) A leak-proof and durable valve seat is lined with a PTFE cup-shaped or O-ring seal with a stainless steel inner core at its outer diameter. The valve seat is made of a large-section tungsten-cobalt hard alloy, and its structure is further reinforced by an alloy corrugated spring;
(4) When the valve is closed, a wedge-shaped shearing action is generated between the V-shaped notch and the valve seat, providing both self-cleaning and preventing the ball core from jamming. It is particularly suitable for high-viscosity, suspension, pulp, and other unclean or fibrous media.
