Product Overview

The Gedhi Vavhavha is a heavy-duty industrial isolation valve designed for reliable on/off service in water, mafuta, gasi, and steam pipeline systems. Manufactured from high-strength ductile iron with renewable metal seat rings (13Cr/Stellite hardfaced), this valve provides excellent corrosion resistance, wear resistance, and long service life in demanding environments. Featuring an OS&Y (Kunze Screw neJoko) rising stem design that provides clear visual position indication — the stem rises when the valve opens and lowers when it closes — this valve enables quick visual verification of valve status. The flanged ends conform to BS 5163, KUBVA 3202 F4/F5, and AWWA standards, kuve nechokwadi chekuenderana nepasi rose pombi masisitimu. Designed and manufactured in accordance with API 600 — the American Petroleum Institute standard for heavy-duty bolted bonnet steel gate valves in petroleum refinery and related applications where corrosion, erosion, and severe service conditions require full port openings, heavy wall sections, and large stem diameters— available in sizes from DN80 to DN400 (3″ to 16″) with Class 150 pressure rating (PN10/PN16/PN25), this valve is suitable for water treatment, kugadzirwa kwemagetsi, fire protection systems, and industrial process lines.

FAQ

Q1: What are the differences between CF3, CF3M, CF8, and CF8M stainless steels?

A: CF8 corresponds to SS304, CF8M to SS316, CF3 to SS304L, and CF3M to SS316L. CF3 and CF3M feature lower carbon content, offering superior resistance to intergranular corrosion, making them suitable for welding applications and corrosive environments.

Q2: What are the advantages of an F316 valve seat with Stellite hard-facing?

A: Stellite is a cobalt-based alloy known for excellent wear, erosion, and galling resistance, particularly at high temperatures. Hard-facing the F316 base material provides an optimal combination of corrosion and wear resistance, ensuring a long service life under demanding operating conditions.

Q3: Why choose gear operation instead of a handwheel?

A: Gear operation utilizes mechanical advantage to make operating large-bore valves (DN200 uye pamusoro) easier and less strenuous. The self-locking mechanism ensures valve position stability without the need for external locking devices. Gear operation is ideal for applications requiring frequent operation or where space is limited.

Q4: What are the maximum working pressure and temperature ratings for this gate valve?

A: Standard configurations are PN10/PN16/PN25 with a temperature range of -20°C to +150°C. Kirasi 150 and higher temperature ratings are available upon request. Please consult our sales team regarding specific requirements.

Q5: Can a gate valve be used for throttling?

A: Aihwa. Gate valves are designed solely for full-open or full-closed service. Using them for throttling can cause erosion of the seat and disc, zvichitungamirira kukukundikana nguva isati yakwana. Globe valves or control valves should be used for throttling applications.
