Eccentric ball valve
Product introduction

Nominal diameter: DN50-2000

Nominal pressure: 0.6-6.4MPa

Connection type: flange connection

Drive mode: manual, electric, hydraulic, pneumatic

Main material: gray cast iron, nodular cast iron, cast steel, carbon steel, stainless steel

Use: petroleum, natural gas, coal gas, liquefied gas, oil and gas transportation engineering; city water supply pipe, heating pipe, water pipelines, water, water diversion project; hydropower power draining sand and slag, gas containing dust particles and fluid etc..

Features: open full size anhydrous loss, no pressure loss, no dielectric deposition; by double eccentric structure, eccentric sphere and valve seat is closed tightly with good sealing performance; opening and closing moment of contact with the sealing surface from small friction sealing and long service life, small operation torque switch off when the ball core density; the seat cover can effectively remove progressive scaling obstacles, suitable for conveying fouling medium; the valve seat and the ball core have the compensation amount, compensation can be adjusted by wear. With two-way sealing valve, adjustable, long life of the sealing structure, compared with its small size, light weight advantages.
