Since the rubber sealing butterfly valve has the disadvantage of being used for throttling, cavitation may occur due to improper use, and the rubber seat may be peeled off and damaged. To this end, a new generation of metal hard seal butterfly valves that solve the cavitation problem was born.
1. The three-eccentric multi-layer metal hard sealing butterfly valve butterfly ring is a soft and hard laminated metal sheet. It has the double advantages of metal sealing and elastic sealing, and has excellent sealing performance regardless of low temperature and high temperature.
2, using three-dimensional eccentric structure, the valve seat and the butterfly plate are almost no friction, the internal parts of the valve are almost no damage when closed; this structure greatly improves the performance of the valve in use. And it has a tighter sealing function.
3. Bushings are installed on the upper and lower parts of the valve stem, and each bushing produces little wear and frictional resistance. This structure completely prevents wear and adhesion, and also increases the service life.
4. The sealing surface of the valve body is made of surfacing alloy steel or stellite hard alloy. The sealing surface of the stainless steel hard sealing butterfly valve is resistant to abrasion, erosion and corrosion resistance;
5, the structure is unique, the switching torque is small, the operation is flexible, labor-saving, convenient, free from the high and low pressure of the medium pressure, and the sealing performance is reliable. Can be used for opening and closing and adjusting equipment.
Yongjia Tezhong Valve Factory specializes in the production of three eccentric butterfly valves, metal hard seal butterfly valves, ventilation butterfly valves and flanged butterfly valves.

Our Dome Lens is an optical window composed of two parallel curved surfaces. Dome lenses are commonly used in meteorology applications, pyranometers, defence applications and often used in high pressure viewports in underwater cameras and submersibles.For this reason our dome offer both high transmission as well as durability. Other application for our dome include visible-range domes for pyranometers and infrared-range domes for pyrgeometers, and as high pressure viewports in underwater cameras and submersibles.
BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.
Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.
