Description
Forged Globe Valves API 602:
Globe valves are mainly installed to modulate or?regulate the volume of the flow. A globe valve is not recommended when a?continuous flow of fluid is required due to the high pressure drop inherent to?the design of the valves itself. This type of valve should always be installed to?ensure that the flow intake enters through the base of the valve seat. The?valve has an arrow stamped on the body to indicate the preferred direction on?flow. Globe valves may be used with fluids containing particles in suspension.
The Features of Globe Valve:
Bolted Bonnet,Outside Screw and Yoke,Rising stems,Metallic Seating surfaces
Stem Design:
The stem is of integral forged desig. The minimum diameter of the stem shall per the standard requirement.
Bellville Spring Loaded Packing Impacking System:
If being requested by the customer, the Belleville spring loaded packing impacting system can be adopted for enhancing the durability and reliability of the packing seal.
Back Seating Design:
All our globe valve have the back seating design. In most cases, the carbon stell globe valve is fitted with a renewable back seat. For stainless steel globe valve, the back seat is machined directly in the bonnet or is machined after welding. When the globe valve is at fully open position ,the sealing of the back seat can be very reliable. However,as per the requirement of API, it is not advisable to add or change placking by the mean of back seating when the valve is pressure containing.
Seat:
For carbon steel globe valve, the seat is ususlly forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer. Renewable threaded seat is used for NPS≤12 carbon steel globe valves.FOR Stainless stell globe valve, integral seat is ususlly adopted, or to weld hard alloy directly integrally. Threaded or welded on seat is also optional for stainless steel globe valve if being requested by the customer.
Stem Nut:
Usually, the stem nut is made of ASTM A439 D2. It is also can be made of copper ally if being requrested by the customer. For large sized globe valve,rolling bearing is fitted at the two sides of stem nut in order to minimize the open and close torque of the globe valve.
Special Globe Valve:
Besides the common globe valves,we also makes cryogenic globe valve. Bellow sealed globe valve, Jacketed globe valve, etc.
