Product Details

Description:

Stainless steel metal seal bolted bonnet flange manual straight type globe valve is a kind of mandatory seal valve, which including five types: BS 1873 globe valve, cryogenic globe valve, DIN globe valve, sdnr globe valve, stainless steel globe valve. When the valve is closed, pressure must be applied to the valve flap to force the seal face to leak. When the handwheel rotates clockwise, the valve stem moves downward, and the valve flap descends to close the sealing surface, cutting the passage. When it is reversed, it is opened, and the valve stem refers to the highest point and the seal acts. Once in the open state, there is no longer contact between its seat and the disc sealing surface, so its sealing surface is less mechanically worn. When the medium enters the valve six from below the valve flap, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium, so the force of closing the valve is greater than the force of opening the valve.

Features:


  • The materials are carefully selected to meet the relevant domestic and foreign standards, with reasonable structure and beautiful appearance.

  • The valve disc and seat sealing surface are wear-resistant, high temperature resistant, corrosion resistant, scratch resistant and long service life.

  • The valve stem is tempered and surface nitrided for good corrosion resistance and scratch resistance.

  • There is no relative sliding between the valve flap and the sealing surface of the valve body when opening and closing, so the wear and the scratch are not serious, the sealing performance is good, and the service life is long.

  • The fluid resistance is large, because the medium passage in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
