Pure nickel is commercially pure (99.6%) wrought nickel.
Weidouli is a leading manufacturer of Pure nickel valves. Normally, Weidouli can supply Nickel 200 & Nickel 201 material valves.
Pure nickel is extreme anti-corrosion under any densities and high temperature caustic alkaline solution, and the anti-alkali crack performance is outstanding. Mainly applies in high-temperature thick alkali corrosive medium condition.
It is distinguished by ductility, strength, and resistance to corrosion and heat. It resists corrosion even at high temperatures and concentrated alkali.
It also has good mechanical properties and excellent resistance to many corrosive environments. Other useful features of the alloy are its magnetic and magnetostrictive properties, high thermal and electrical conductivity, low gas content, and low vapor pressure.
Upward discharge valves
Design Features
The gasket is placed in the concave groove of the valve body, the gasket can keep the elasticity for a long time and the sealing is reliable.
Integral forging valve core design, with better strength.
Enlarge the size of the stem and connection rod made the valves more stable and firm.
Waist drum structure valve bodies have good streamline, it can increase flow capacity and reduce medium deposition.
Spring-loaded packing design provides more reliable sealing and realizes packing seal online adjustment
Valve core have guide device to protect the stem from deviation
