Bright Stem Protective Gate ValveIt Is A Cut-off Valve With A Protective Structure Added On The Basis Of Ordinary Rising Stem Gate Valves. Its Core Function Is To Control The Flow Of Pipeline Fluids, Combining The Advantages Of Intuitive Rising Stem Valve Status And Additional Protective Performance. It Can Protect The Valve Stem And Core Components From External Erosion, And Is Widely Used In Industrial And Municipal Pipeline Systems With Complex Working Conditions And Long-term Protection Requirements. It Is A Practical And Protective Basic Control Valve.

Structurally, It Continues The Core Structure Of The Rising Stem Gate Valve, Mainly Consisting Of The Valve Body, Gate Plate, Rising Stem, Handwheel, Packing Box, And Sealing Components. It Also Adds A Core Protective Component - The Valve Stem Protective Cover, Which Is Mostly Made Of Stainless Steel Or Corrosion-resistant Plastic And Can Fully Wrap The Exposed Valve Stem To Avoid Damage From Wind, Rain, Dust, Medium Corrosion, And External Collision. The Valve Body Is Mostly Made Of Ductile Iron And Cast Steel Materials, Which Are Precision Cast. The Gate Can Be Selected With A Wedge Or Parallel Structure. One End Of The Valve Stem Is Connected To The Gate, And The Other End Is Connected To The Handwheel Through The Packing Box. The Entire Opening And Closing Process Is Visible.

The Core Features Are Distinct, With Dual Advantages Of Visible Stem And Protection: The Opening And Closing Status Is Intuitively Visible, And The Opening Degree Can Be Determined By The Height Of The Valve Stem, Avoiding Misoperation; Outstanding Protective Performance, Protective Cover Effectively Extends The Service Life Of Valve Stem, Valve Body Is Treated With Anti-corrosion, Suitable For Complex Media And Outdoor Working Conditions; Reliable Sealing, The Gate And Valve Seat Are Tightly Fitted, Without Any Leakage Hazards; The Structure Is Sturdy And Wear-resistant, Easy To Maintain, The Valve Stem Is Exposed And Protected, And There Is No Need To Disassemble The Entire Valve For Maintenance And Replacement Of Packing. The Failure Rate Is Low, And The Handwheel And Transmission Mechanism Are Strictly Prohibited From Collision Or Lifting.

Widely Applicable In Various Fields Such As Municipal Water Supply And Drainage, Petrochemicals, Electricity, Fire Protection, Etc., Especially Suitable For Outdoor, Dusty, And Highly Corrosive Scenarios, Such As Urban Water Supply Networks, Sewage Treatment Plants, Outdoor Heating Pipelines, Etc. Compared To Ordinary Rising Stem Gate Valves, It Has Better Protection And Can Adapt To Harsh Working Conditions, Ensuring Long-term Control Of Pipeline Opening And Closing. It Is An Ideal Choice For Valve Protection Scenarios, Suitable For Medium And Low Pressure, Normal To Medium Temperature Working Conditions, And Can Handle Various Fluids Such As Water And Oil.
