JQW61Y320- Welded ball Seal Stop Valve,Welded ball Seal Stop Valve,Seal Stop Valve

JQW61Y320- Welded Ball Seal Stop Valve Also known as spherical seal stop valve, the valve core is spherical sealed, butt-welded connection, manual switch, straight-through stop structure, the sealing surface material of the valve core and valve seat is surfacing STL alloy, nominal pressure PN32MPa, nominal diameter DN15-DN50, valve body material A105 applicable temperature ≤425℃, valve body material 12CrMoV applicable temperature ≤570℃ The valve body material is F91, with an applicable temperature of ≤670℃. The pipe connection dimensions are made in accordance with the standard. BW butt welding connection is adopted (the welding bevel should be in accordance with the provisions of the Electric Power Industry management standard 78DG or the dimensions provided by the user).

Purpose

It is widely applied in fields such as chemical engineering, petrochemicals, petroleum, papermaking, mining, power, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal services, mechanical equipment matching, electronics industry, urban construction, etc.

Characteristics

A valve in which the opening and closing member (disc) moves up and down along the axis of the sealing surface of the valve body has a relatively short opening and closing stroke of the valve stem, and it has a very reliable opening and closing function

Alloy steel valves have the characteristics of withstanding high temperatures and high pressures.

The sealing surface is prone to wear and scratches, has good sealing performance and a long service life.

Compact structure, good opening and closing performance, small height and convenient maintenance.

The connection points of the welded structure are not prone to leakage.

It is widely applied in fields such as chemical engineering, petrochemicals, petroleum, papermaking, mining, power, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal services, mechanical equipment matching, electronics industry, urban construction, etc.
