Detailed Product Description

Features :

• Original design and sistinctive structure
• Labor saving operation and quick open-close
• Adjustable and replaceable seal ,dependable sealing,low fluid resistance ,and energy conservation .

Working Pinciple :

• Disc closed ,Medium enters form the upstream of seat. Under the force of medium ,sealing ring will get close to the sealing face of disc , and the elasticity and deformation of sealing ring will function to guarantee the sealing performance.
• Disc closed , Medium enters form the downstream of seat . Under the extrusion of press board ring , sealing will overcome the acting force of medium and get close to the sealing face of disc , thus to guarantee the sealing performance.
