Fetures

Central structure

Valve plate’s center position auto tune

Variety of actuators are optional

Body’s surface are covered with seat ring, no need to worry about body will be corroded.

Central valve of bi-directional compression

Rubber lined inner surface cut off contact between metal and fluid

Adoption of light weight and high strength large diameter Hollow Slab

Dependable valve rod hole seal structure

Excellent bearing with low friction and good corrosion resistance

Short structure can save space for installation effectively
