Tilting Check Valve

DENZ-C10 tilting disc check valve (also known as a tilting check valve) is used in pumping applications to prevent backflow into the system. The interior parts of all the parts are made of stainless steel or coated with an epoxy that is approved for drinking water use. Depending on the application, the valve can either be fully coated with ebonite or rubber if it is intended for sea water use.

• ENGJS500-7 Ductile iron body and bonnet for high strength and impact resistance.

• This valve is designed as a resilient seated type. There is an option to order the metal seated type for specific orders.

• As a default, the sealing ring on the disc is EPDM. Various options are available, including NBR and VITON.

• Drop-tight sealing is extended with a solid/one-piece block molded T-shaped disc sealing ring.

• The counter lever length and weight can be adjusted to adjust the speed of the open/close. DENZ-C11 Tilting check valve with hydraulic damper is recommended for

controlling speed.

• Both sides of the valve can be fitted with the arm and counterweight. Counterweights can be customized by the end user according to their usage. It is the responsibility of the DENZ technical team to provide the necessary support to the end user.

• When the valve is connected to the pipeline, the sealing can be easily replaced. For this process, the valve does not need to be removed from the pipeline. A new sealing can be installed by removing the bolts of the retaining ring.

• A welding seat made of SS308 LSI grade stainless steel is manufactured on the body using automatic welding machines and microfinished precision milling. The disc sealing ring applies equal pressure to all points of the welding seat once the disc is fully closed.

• The shafts are equipped with corrosion-resistant bronze or brass bushings.

• Due to the double shaft design, pressure loss is minimized and energy efficiency is increased.

• The pumps require less energy to operate due to the low torque advantage.

• Internal and external coatings with an average thickness of 250 microns are applied to the disc and body.

Depending on the application, higher coating thicknesses can be applied.

• Coatings that meet WRAS hygienic standards are available upon request.

• During the installation process, it is important to consider the direction arrow on the body.

• AISI420 stainless steel spindle for high strength and corrosion resistance. Upper grade shaft materials can be used.

• 100% of the valves are subjected to Hydrostatic tests according to EN 12266-1. Pressure for seat: PN x 1.1 , for

shell: PN x 1.5
