Product Specification

DINKONDA GLOBAL Power Plants Special Class600LB And Class900LB Forced Sealed American Standard Flange Connection Globe Valves, One-way Shut-off Valve

Product Overview
This series of American standard flange globe valves, with pressure ratings of 600LB and 900LB, adopts a flange connection form and belongs to a forced sealing valve. By relying on the pressure of the valve stem, the sealing surface of the valve disc is tightly adhered to the sealing surface of the valve seat, achieving pipeline connection and throttling adjustment. The product is designed and manufactured strictly in accordance with American API and ASME standards. The valve body can be made of materials such as WCB, F304, F316, etc. It is suitable for use in petroleum, chemical, thermal power, metallurgy and other working conditions to control the flow and cut-off of steam, oil, water, and corrosive media. It has the characteristics of high pressure resistance, reliable sealing, and sturdy structure, and is suitable for use in high-pressure pipelines.

Structural Composition
1. Valve body: spherical valve body structure, flange connection end, optimized flow channel design, capable of withstanding high-pressure loads, materials can be selected from carbon steel and stainless steel, suitable for different media corrosion requirements.

2. Valve seat and disc: The sealing surface can be welded with hard alloy, which is wear-resistant, erosion resistant, and has good abrasion resistance; Adopting a flat/conical sealing structure, it is forcibly compressed when closed to achieve a tight seal.

3. Valve stem: using quenched and tempered valve stem, surface nitriding treatment, corrosion-resistant and wear-resistant; The open stem structure allows for intuitive observation of the valve opening height, and the threads do not come into contact with the medium, thereby extending the service life.

4. Valve cover component: bolt clamped valve cover, gasket sealing, easy disassembly and maintenance; The stuffing box is equipped with flexible graphite packing, which is resistant to high temperature and high pressure, effectively preventing medium leakage.

5. Drive handwheel: manual disc handwheel, rotate the valve clockwise to close and counterclockwise to open, with moderate operating torque; Electric and pneumatic actuators can be selected according to demand.

6. Flange connection end: American standard RF raised face flange, in compliance with ASME B16.5 standard, easy to connect and install with on-site pipeline bolts.

Product Features
1. Reliable sealing performance: The sealing surface is welded with hard alloy, which is resistant to erosion and wear, and has a tight seal under high pressure conditions with low leakage.

2. American standard high pressure rating: covering 600LB and 900LB pressure ratings, capable of withstanding high pressure in pipelines, and suitable for high-pressure process systems in thermal power and petrochemical industries.

3. Clear stem structure: The valve stem extends out of the valve cover, and the valve opening is visible to the naked eye, making it easy to determine the working status of the valve on site.

4. Easy maintenance: The valve cover is connected by bolts, and the packing, valve stem, and internal seals can be disassembled and replaced on site without the need to remove the valve body as a whole.

5. Flexible material configuration: WCB carbon steel valve body is suitable for steam and oil products; 304/316 stainless steel is suitable for various corrosive media.

6. Throttle function: Globe valves can be used for pipeline throttling regulation, but should not be used for small opening throttling for a long time to avoid erosion and damage to the sealing surface.
