Features and advantages

Installation flange can be installed directly in line with the ISO standard driver.

The sleeve will cover the shaft sealing, improve maintenance reliability.

The upper and lower shaft made of stainless steel has the function of anti explosion.

Unique square neck design can be used without fasteners. This design can prevent the replacement of errors and eliminate the potential impact of loose parts, and can eliminate the loose parts with the flow of media and the possibility of damage to the equipment.

Shaft seal can effectively prevent leakage of media.

The valve plate is made of nodular cast iron. Valve body and valve plate can achieve 360 degree continuous contact. The streamlined shape of the valve plate has the advantages of large opening, and can increase the flow coefficient.

Clamp valve body greatly reduces the weight of the valve installation, easy operation, installation and maintenance.
