Valmax Globe Valves

The stem axis of the globe valve is vertical to the sealing surface of the seat. The stem has a relatively shorter opening or closing travel with very reliable cutting operation, so that this kind of valve is very suitable for cutting and regulating medium as well as throttling.The most important feature of the steel globe valve of Valmax Company is the design of conical surface of the valve disc and full guide rail, and the middle shaft sealing can pass the USA VOC leakage test. Valmax Company can provide trims and shells of various materials for the globe valve in the same way as for the gate valve.
