Product Features:
1.Outside Screw and Yoke: The external side of the stem is threaded, while the section inside the valve is plain. Valve stem threads are isolated from medium by packing, which keeps the stem threads outside the valve body to avoid damage from high temperatures, corrosives, and solids within the valve. The external screw can be maintained from the outside, making it the preferred choice for demanding applications.
2.Body/Bonnet Connection: KAMROO globe valves are available with bolted and pressure-sealed bonnet, depending on its pressure rating or customer requirements.
3.Body/Bonnet Sealing: KAMROO offers stainless steel with graphite spiral wound gaskets for bolted bonnet globe valves in pressure rating Class 15 to Class 600, and Octagonal ring fittings as standard for bolted bonnet globe valves in pressure rating Class 900 and above. Pressure seal bonnet design are usually used for valve pressure rating Class900 and above to make it sealed. The common used material for the gasket is flexible steel ring or graphite.
4.One-piece Forged Material Stem: The stem of the globe valve provided by KAMROO is made of one-piece forged material. The precision thread machining and high surface finish of the stem ensure the reliable performance of the stem and the perfect tightness of the packing contact area.
5.Stem Packing: Molded flexible graphite is used for packing material. PTFE or composite packing material can also be used according to customer requirements. The inner surface of the stuffing box has a high surface finish at the contact area with the packing. The surface of the contact between the valve stem and the packing has been precisely machined to achieve the required high finish and density, ensuring the reliable sealing of the valve stem.
6.Back Seat Design: KAMROO globe valves adopt the back seat design. In most cases, the carbon steel globe valve is fitted with a renewable back seat. For the stainless steel globe valve, the back seat is machined directly in the bonnet or after welding. The sealing of the back-seat is reliable when the globe valve is in a fully open position.
7. Various Disc Types: KAMROO globe valves are available of plug type disc, ball type disc, needle type disc and parabolic type disc.
Plug type disc is most common used type of disc. It has a flat surface, designed to permit flow passage or stop without regulation, which is suitable for positive shut off service.
Ball type disc is designed for low-pressure and low-temperature systems with throttling capability, but is more commonly used for shut off service.
Needle type disc is designed to have better flow rate than other discs, which is commonly used for throttling service.
Parabolic type disc is similar to the ball type disc but with higher flow regulation capacity and better wear-resistance capability.
8.Replaceable and Integral Seat Design: KAMROO cast steel globe valves are available of both replaceable seat and integral seat design. Carbon steel globe valves are usually with replaceable seat ring either threaded with welding or welded on to body directly. For stainless steel and high temperature alloy steel globe valves, it is recommended that the valve seat is designed as integral valve seat or body sealing surface with hard surfacing welding.
