Hard Seal Flange Gate Valve for Gas Water Oil Heavy Duty Manual Valve Z41H-16C Cast Steel Normal Tem

Product Name: Spark DN65 Cast Steel Flanged OS&Y Gate Valve
This is Spark’s DN65 cast steel flanged outside screw & yoke (OS&Y) gate valve, a core on-off control component for industrial fluid pipelines—widely used in scenarios such as chemical pipelines, oil transportation systems, power auxiliary water networks, and industrial process pipelines. Made of cast steel WCB, it has excellent temperature/pressure resistance and corrosion resistance, adapting to multiple industrial media; the OS&Y handwheel design allows intuitive judgment of the valve’s opening/closing status, the flange connection adapts to industrial standard pipelines, and the metal hard-seal structure ensures reliable sealing during on-off operations. It is a highly reliable equipment for pipeline on-off control in industrial scenarios.

Frequently Asked Question

FAQ

What is a pressure relief valve?

The Forede pressure relief valve (PRV) is a mechanical device that releases gas or liquid from a system when the pressure exceeds a predetermined limit. PRVs are used to prevent over-pressurization, which can damage machinery or people

What is the purpose of pressure relief valve?

The PRV Pressure relief valve is a safety device that prevents a system from becoming dangerously pressurized by automatically releasing excess pressure. PRVs are used in many industrial settings, including power plants, chemical plants, and refineries, as well as in boilers, tanks, and pipelines.

How should i install the pressure relief valve?

The pressure relief valve came with flange end connection, please inform us the flange standard you need before placing the order to ensure the PRV valve could compatible with exist system.

What is the shipping methods?

It could be shipped by sea,by air or by express(EMS,UPS,DHL,TNT,FEDEX and ect). Please confirm with us before placing orders.
