● Frictionless Switching: The unique design prevents friction against the valve seat, reducing wear compared to traditional valves.
● Single Seat Design: This design ensures no leakage downstream and prevents pressure build-up inside the valve.
● Self-Cleaning: The media flows 360 degrees around the seal when the valve core moves away from the seat, cleaning off any debris.
● Low Torque Required: Without friction on the sealing surface, the valve turns easily.
● Durable Hard Seal: The valve core's sealing surface is reinforced with hard alloy, making it reliable even in harsh conditions.
● Double Eccentric Design: This feature combines the best aspects of various valves, handling extreme conditions like high and low
temperatures, frequent operation, and bidirectional shutoff more effectively.
● Full Bore Design: The design ensures an open, unobstructed flow path without any dead zones or build-up, eliminating the need for
pressure relief.

The hard-sealed butterfly valve is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are also higher than those of cast steel parts.
This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
