Body
Built in one piece in Wafer, Lug and Flanged configurations, they are designed to ensure maximum safety and reliability. It has an extended neck that facilitates access to the rod sealing system through a housing for the Gasket Preme. The top flange allows direct coupling of actuators without the need for brackets – eliminating the possibility of backlash between these components.

Disco
Cast stainless steel disc ASTM A-351 Gr. CF8M bi-eccentric, reducing friction with the seat and increasing its useful life, in addition to allowing flow at small opening angles providing low pressure drop and torque reduction.

Sealing seat
Fixed to the body by a device that eliminates the use of counter-flanges or any other part external to the valve, to ensure its sealing even when installed at the end of the line.

Upper shaft seal
Adjustable PTFE gaskets with a tightening system that eliminates the need to remove the actuator for adjustments.

Lower shaft seal
Lower shaft sealing made through O'Rings chamber located on the rods and bearings.

Fixing the shafts to the disc
Shafts are fixed to the disc using conical pins in stainless steel ASTM A564 condition H1075 (17-4PH) with 1:50 connection with screws and lock washers on one end to ensure perfect fixing.

bearings
Constructed of self-lubricating polymer composite material.
