What 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 […]
