What’s the top entry ball valve? When it comes to the body style, ball valves can often be divided into side entry ball valve, top entry ball valve and fully welded ball valve. Top entry ball valves are valves that assembled its ball from top side part. It just like a globe valve that has body and bonnet except the trim part utilize a ball type. It comprises one single body. Top entry ball valves are used in piping systems where the top of the valve can be removed to gain access to... -
Short Lead Time for Fire Gate Valve - Resilient Seated gate valve – Nortech
Product Detail: What is Resilient Seated Cast Iron gate valve ? Resilient Seated Cast Iron gate valve has a plain valve bottom allowing free passage for sand and pebbles in the valve. If impurities pass as the valve closes, the rubber surface will close around the impurities while the valve is closed. A high-quality rubber compound is soft enough to absorb impurities, yet strong enough to wash the impurities through when the valve is opened again. This means that the rubber surface will rega... -
Low MOQ for Fuel Ball Valve - Floating Ball Valve – Nortech
What’s floating ball valve? A Floating Ball Valve uses a rotating ball and a stem that provide on/off flow control. The floating ball valve utilize natural line pressure to press and seal the ball against the downstream seat. The line pressure is exposed to a greater surface area – the entire upstream face of the ball, which is an area equal to the actual pipe size. A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts t... -

Hot sale Wras Butterfly Valve For Water - PTFE lined butterfly valve – Nortech
Product Detail: What is PTFE lined butterfly valve ? PTFE lined butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc... -
