Upload eccentric half ball product features as follows: 
 , Seal (spool valve seat) - bi-metal, metal spherical ring seal, fire and explosion; 
 , Sealed tight, sealing of the valve plug and seat spherical line contacts rely on the three-dimensional eccentric zero leakage; 
 Spool seal pair left the compensation amount, the valve using a longer time to find the seal pair wear only loose hands the wheel side of the limit bolt is turned off and then turn a little, can achieve a reliable seal, extend the service life . 
 Can compress sets of twist off, adjust or replace the valve seat, the valve can still be used, to avoid the drawbacks of the existing numerous valve seal failure scrapped. 
 Top entry eccentric half ball industry scope of 
 Universal valve: rational design, compact structure, small flow resistance, good sealing, light and flexible, especially suitable for low pressure pipe network for water, sewage, steam, pulp and other media, preparation of electric, pneumatic devices, can achieve long-range automation operation. (Water, steam, sewage, paper pulp, slurry and other non-corrosive medium) 
 Pulverized coal injection only: used to control the dusty gas, pulverized coal injection of particle-fluid and solid transport is the ideal equipment widely used in metallurgy, mineral processing, power production process in the blast furnace pulverized coal injection coal pulverizing system and dust control systems of various pipelines. It uses straight-through structure, flow unobstructed, does not appear to fouling and clogging, sealing the Co-Cr-W alloy, anti-erosion wear resistance after special heat treatment, valves, while valves with automatic compensation for the performance of eccentric spherical through the adjusting screw on the worm gear, make the valve in the case of a certain degree of wear, you can still achieve the effect of re-sealed. (Dusty gas, particle-fluid) 
 Petroleum and Chemical-specific: for the petrochemical industry use of high pressure, high temperature, full of flammable, explosive, corrosive media of general weak acid weak base, with good sealing, corrosion resistance, lightweight hoist, automatic removal of the fouling of the valve face characteristics of objects, etc., apply to the transmission medium such as crude oil, heavy oil and oil cracking, the food production process. (Oil, gas, gas, water, etc.) 
 Blast furnace gas, gas-specific: the seal pair of Cr-Mn-Si carbide, refractory explosion-proof anti-static, sealed Vice anti-high temperature 560 ° C, anti-corrosion and anti-occlusion capacity is six times more than the stainless steel Sealing is particularly suitable for gas, coke oven gas, water gas, liquefied petroleum gas, natural gas pipeline and pressure on the gate station. (Blast furnace gas, natural gas, dust gas, etc.) 
 Slurry mixed fluid-specific: transportation easy precipitation fouling, process valves in the fluid medium between the two mixed up the best crystallization process of the solution, slurry, the slurry ash can get rid of barriers to scale in closed successfully shut down . The novel structure and unique design, with high efficiency, good wear resistance, sealing, reliable, easy operation, open and close rapidly, and long lifetime. (Including process slurry, the slurry of ash and other particulate matter transport) 
 Pipeline special: half ball is a straight-through, no necking, body channels and pipelines to connect the pipe into a straight tube the same cross-sectional area equivalent resistance is less than the reduced diameter, fully open and fully closed simply by turning 90 degrees can be achieved to facilitate long-distance pipeline transmission and control. (Pulverized coal injection and gas transportation).
