- FAF2280D Series Tilting Check Valve The tilting check valve con- sists a circular disc with conical rim, hinged about a fixed pivot above its center-line and offset from the plane of the seat, sealing against a body seat clamped between the two sections of the valve body. FAF 2280D hydraulic brake system can be assembled to disc closing unit if it is required at project. The rate of closure can be controlled due to tilting check valve with hydraulic brake system and the system passes to static position slightly. The installation equipment protected from impact strength.

The sealing that can be made of EPDM, NBR and VITON materials can be dismantled and replaced easily on field conditions.
y Inner and outer surfaces of the valve is coated with 300 microns thickness of fusion bonded epoxy. Higher thicknesses are availabe upon request.
y Hydraulic braked swing check valves prevent the occurrence of hard brakes due to the effect of the braking system and virtually elimi- nate the noise, ram impact and damage.
y 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.
y Low moments are obtained by decreasing the friction through self lubricating bushings.
y Can bear high stretching stresses on the pipeline through the duc- tile iron body and disc.
y High impact resistance.
y Reduces the pressure loss through the disc designed in accordance with the direction of flow.
*** Pressure loss is at minimum level by double shaft design.
*** Countervalve 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 clapper opens depending on the flow rate and moves freely depending on the flow.
*** The position adjusts to the working conditions thanks to the ad- justable weight.
*** Lifting lugs and feet ease the balance during transport and instal- lation.
*** Hydraulic braked swing check valves prevent the occurrence of hard brakes due to the effect of the braking system and virtually elimi- nate the noise, ram impact and damage.
*** The closing speed can also be adjusted in accordance with the op- erating conditions in the swing check valves with hydraulic brake.
*** With the o-rings on the bearing bushings, disc pin holes are protect- ed 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.
*** Inner and outer surface of the valve is coated with minimum 300 micron thickness FBE coating.
