The Flow Resistance of Shut-off Valve
The valve stem axis of the shut-off valve is vertical to the valve seat sealing surface. The opening and closing strokes of the valve stem are relatively short. And there’s a very reliable shut-off action, which makes this kind of valve very suitable for shutting-off, regulating, and throttling of the medium. Once the valve flap […]

What are the Uses of Shut-off Valve? 1. The structure of the shut-off valve is simpler than that of the gate valve. It’s easy to manufacture and repair. 2. The sealing surface of the shut-off valve is not easy for wear and abrasion. The sealing performance is good. There is no relative sliding between the […]
Read moreWhat is a Shut-off Valve?
A sanitary shut-off valve is a kind of mandatory sealed valve. When the valve is closed, pressure must be applied to the valve gate to ensure the sealing surface doesn’t leak. When the medium enters the valve from below the valve gate, the resistance the operating force needs to overcome is the friction between the valve stem and […]
Read moreIntroduction of Forged Steel Flange Shut-off Valve
A forged steel flange shut-off valve is a kind of valve whose closing member (valve flap) moves along the centerline of the valve seat. According to this type of movement of the valve flap, the change of the valve seat outlet is proportional to the stroke of the valve flap. Because the opening and closing […]
Read moreThe Features of Duplex Stainless Steel Shutoff Valves
The excellent performance of an all-forged duplex stainless steel sanitary shutoff valve is determined by the performance of the materials and the structural characteristics of the valve itself. So, let’s first take a look at the characteristics of the duplex steel. The so-called “duplex stainless steel” is a kind of steel in which the ferrite phase […]
