Features
- 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.
