● Adjustable Stem Packing
Fully adjustable, field-replaceable stem seal system that meets international fugitive emission certification standards.
● Inspection Port Design- Field Replaceable Seatand Seal System
Field replaceable seats and seals extend the overall life of the valve, minimize downtime, and reduce the need for expensive non-current repairs or overall replacement.Metal-to-Metal Seals
Frictionless metal-to-metal seals are inherently fire resistant and fire tested, while
meeting bidirectional zero leakagerequirements for a variety of critical applications.

The Power Plant Gate Valve is mainly suitable for the pipelines of various systems of thermal power station, cutting or connecting the pipeline medium. Compared with other valve products, the Power Plant Gate Valve is characterized by high temperature and high pressure. It is counted as a unique and closely sealed structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The Power Plant Gate Valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the seal of the gate on the valve seat is correspondingly accurate. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
The Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
Self-Operated Micro-Pressure Regulator does not require additional driving energy and is a kind of energy-saving control device; it is a specialized product for current most popular nitrogen sealing system of storage tanks.
