Characteristics

The valve cavity adopts a pressure self-tightening sealing structure, and the higher the internal cavity pressure, the better the sealing performance.

The sealing surface of the valve disc and the valve seat is made of stellite stellite cobalt-based hard alloy, which is wear-resistant, high-temperature resistant, good in anti-scratch performance and long in service life.

The bonnet stuffing box is reasonable to try, the filler is added with corrosion inhibitor, the seal is reliable, and the switch is stable.

The valve has an upper sealing structure to ensure that the valve stem does not leak when the valve is opened.

Both ends of the branch pipe are butt welded joints to meet different takeover requirements.

The products are designed and manufactured according to ASME B16.34 and E101 standards and can be used with imported equipment.

High temperature creep resistant design.

The valve stem is made of nitriding type precipitation hardening stainless steel.

Because the valve body is Y-shaped design, the channel mutation is slowed down, thus reducing the pressure loss; for the medium that is easy to stutter, it is more advantageous to choose the Y-shaped seat.
