Globe Valve
- Offered precise throttling and control.
- Excellent capabilities to control the fluids with applying the needle disk.
- Minimization of the seat damages due to the cavitation.
- Minimization of the vibration problems applying the disk guide.
- Widely used to regulate fluid flow in both on/off and throttling service.
- The internal passages within the valve divert this flow through two 90-degree changes of direction which results in pressure drop and turbulence significantly higher than straight-through valves such as gate or ball valves.
- The amount of force necessary to close a globe and angle valves against pressure is much higher than for gate valves, but the distance the stem must travel from full open to close is much less.

Non-Bonnet Globe Valve
- No possibility of leakages between Body and Bonnet due to integral type.
- No need long time for maintenance and repair for the valve due to easy dismantle within 1 minute.
- PWHT is not required due to integral Body and Bonnet . PWHT is required and difficult to perform for Seal Welded Bonnet type.
- Do not loose the Gland Bolt & Nut under operation.
