Soft seal gate valve advantages

The soft gate valve is the replacement of the traditional gate valve. It uses the elastic gate to compensate the slight deformation and achieves a good sealing effect. The valve has the following advantages: 1. This valve is designed with a full coverage of high quality rubber on the gate surface, , Long life, no leakage and so on. 2, the bottom of the valve body design without grooves, so the flow resistance is small, to prevent the accumulation of dirt caused by valve leakage or damage and so on. 3, the body cavity for spraying treatment, long-term use of non-corrosive and rust, effectively prevent secondary pollution. 4, easy to install, can achieve online quick repair. 5, valve bonnet are made of ductile iron, higher toughness, to avoid cracking during use or transport; stem for stainless steel, to avoid rusting phenomenon. 6, the use of three "O" ring design, tight seal, a substantial reduction in frictional resistance and environmental health, there is pressure to keep the water can replace the "O" type rubber ring features.

Plano-Convex Spherical Lens

We can manufacture various shape and special material optical lens.The coating for lenses not only the normal BBAR coating,but also including dichroic coating and super broad band antireflective coating.

Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications. They are also useful in a variety of applications involving emitters, detectors, lasers, and fiber optics. Coated versions have optimum light transmission. Available in a wide variety of diameters and focal lengths.
The uncoated lenses are ideal for a multitude of optics and photonics applications, as well as biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.

The coated lenses can be utilized in a host of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
