Ensures 100% sealing with the “T” section ring fixed to the outer diameter of the disc fully facing the seat surface inside the body perimeter made of stainless steel welding.
The sealing that can be made of EPDM, (NBR and VITON) optional materials can be dismantled and replaced easily on field conditions.
Inner and outer surfaces of the valve is coated with (250) microns thickness of fusion bonded epoxy.
Higher thicknesses are availabe upon request.
Low moments are obtained by decreasing the friction through self lubricating bushings.
Can bear high stretching stresses on the pipeline through the ductile iron body and disc.
High impact resistance.
Pressure loss is at minimum level by double shaft design.
Countervalve weight allows installation of both horizontal and vertical pipes on the right and left sides of the mill, counterweight, and lever on both sides of the check valve.
The disc opens depending on the flow rate and moves freely depending on the flow.
The position adjusts to the working conditions through to the adjustable weight.
Lifting lugs and feet ease the balance during transport and installation.
Sealing gaskets made of EPDM, NBR or VITON supplied according to operating conditions and demand can be disassembled and replaced easily in field conditions.
With the o-rings on the bearing bushings, disc pin holes are protected against corrosion (Dry shaft).
Retaining ring is assembled to the disc with imbus bolts, the disc is protected against corrosion by placing o-rings under the bolts.
