NRS metal seated gate valve

Sealing performance: hard seal gate valve sealing surface made of brass which has high hardness, wear resistance and corrosion resistance, can be in high temperature, high pressure and strong corrosion environment to maintain good sealing performance. But relative to the soft seal gate valve, its sealing performance may be slightly inferior.
High temperature resistance, wear resistance, corrosion resistance: due to the use of metal sealing surface, hard seal gate valve in high temperature, high pressure and strong corrosion environment performance is more stable.
Good mechanical properties and long service life: The hard-sealed gate valve has good mechanical properties and can withstand greater pressure and torque, so its service life is relatively long.
Low fluid resistance: The fluid channel of the hard seal gate valve is designed reasonably, and the fluid resistance is small, which can reduce the energy loss of the fluid.
Opening and closing labor-saving: the opening and closing operation of the hard seal gate valve is relatively labor-saving, easy to operate and maintain.
