DN50 DN65 DN80 DN500 DN1000 Cast Iron/Cast Steel Pn16 Steam Bellow Seal Water Globe Valve

Product Description

 
Cast Steel Globe Valves are designed to close off, open up or throttle the flow in a pipeline. The disc is designed to completely stop flow and form a tight seal with pressure under the disc. In the 10% open position to full open position, globe valves are effective in throttling line pressure. Continuous throttling at less than 10% open may cause excessive vibration, noise, wear and damage to discs and seats.

Wear resistance, high-temperature resistance, corrosion resistance, good scratch resistance, and long service life;
Compact structure with obvious features in appearance.

• Seal-welded seats

• Bosses for taps & bypass

• Graphite packing

• Ring Joint gaskets Class 600-2500

• Fugitive emission tested

• NACE MR-01-75

Cast Steel Globe Valve are made up of three parts: a hand wheel, a bonnet, and a body. The stem is housed in the bonnet, and it screws up and down in the bonnet when the hand wheel is turned. A disk or plug is a small section at the end of the stem that can be metallic or non-metallic and come in a variety of shapes, reliant on the use.

A seat is contained in the globe-shaped body to which the valve is entitled. The seat is a metal frame with a hole that separates the body into two chambers and lets fluid pass through. Fluid flows up through the opening in the seat when the valve is open.

When a globe valve plug or disk is kept in the seat, fluid flow is clogged. When the valve is open, the fluid must revolutionize directions twice to pass through the seat, resulting in substantial head loss.

Globe valves can throttle or control flow, which is one of their vital advantages. They might be partially open in addition to being closed or open. This lets you modify the flow without having to stop it.
