● The length of the structure is short series, the valve is light in weight, and the pipe support frame can be saved.
● The valve in the process of opening and closing the gate can scrape off the attached medium by itself, which is conducive to sealing.
● Knife gate is conducive to cutting off the medium, slagging, valve operation unblocked.
● Valve adopts clamp connection. Wedge limit provides sealing force and reliable sealing.
● Wear-resistant bushings of different materials can be provided according to requirements to extend the service life of the valve.
● Drive device (electric, gearbox, pneumatic, hydraulic) can be optional.

The valve disc of the Cryogenic Lifting Check Valve adopts a vertical lifting structure and is equipped with a cobalt-based alloy sealing surface. It can achieve rapid response and reliable sealing when the medium pressure changes. The product complies with BS 6364 and API 6D standards and is suitable for the transportation systems of low-temperature media such as LNG and liquid oxygen. The working pressure can reach Class 2500 and meets the strict working conditions requirements in the petrochemical and air separation fields.
An energy-saving control valve without external energy sources, used for flow control in process equipment involving non-corrosive liquids, gases, steam, etc.
The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
