-- NTGD Valve is an ISO 9001 certified company which was founded by a team of engineer with more than 30 years of experience in the supply of industrial valve. NTGD valve specialized in industrial valve supplies, including ball valve, gate valve, globe valve, check valves, strainers, plug valves, and butterfly valves in carbon steel, stainless steel, duplex stainless, and alloy materials. They offer a variety of industrial valves for natural gas applications such as shut off, regulation of fluids like gas, steam, oil, and water, etc.Gate Valve:
Gate valves are specifically designed to start or stop a flow where a straight-line fluid flow and a minimum flow constraint are required. In operation, these valves are pretty much kept either entirely open or completely closed. When rotated to open, the gate valve's disc is withdrawn, allowing the contents to flow. Although it provides the valve with strong shut-off properties and is bi-directional, it cannot be opened or closed easily and are susceptible to vibration when opened.
Gate valves at NTGD are engineered with built-in protection in precision and total traceability of main valve parts. The wedge is entirely vulcanized with oil and gas safe rubber compounds. It has a strong longevity thanks to the ability of the specialized rubber to recover its original form, the double bonding vulcanization method, and the durable wedge construction. The pressure-replaceable stem sealing device, the high-strength stem, and the extensive corrosion safety guarantee superior reliability.Globe Valve:
Normally used for cooling water systems, transporting fuel oil, and turbine oil systems, the globe valve (https://www.ntgdvalve.com/globe-valve/
) is a linear motion mechanism used to stop, start and control traffic.
In the natural gas industry, a globe valve is used for isolation and throttling facilities, the globe has become the most popular type of valves in the world. With a good shut-off functionality, available in T, Y, and angled patterns, and easy-to-machine valve seats, it's easy to see why they're so popular.
The valve disc and the valve seat are the sealing components of the globe valve. To shut the valve firmly, the corresponding surface of the valve disc and the valve seat can be grinded and corrosion-resistant and wear-resistant components such as Stellite 6 and stainless steel should also be welded to the sealing surface. The valve disc and the valve stem of the globe valve are designed to provide a flexible linkage for the valve disc and the valve stem fitting.
