Globe Valves and Steam Stop Valves in Bhopal

Globe valves shut off or regulate flow with a disc that lifts off a seat, so they are used where a line must be throttled as well as isolated, such as test, bypass and drain lines and steam and oil lines. Fire Protection System supplies bronze, gun metal, cast iron, forged steel and cast steel globe valves and steam stop valves from Sant Valves, Kartar Valves and Zoloto in Bhopal and across Madhya Pradesh.

How to choose

Start with the fluid and duty. For water and oil lines up to 100 mm, Sant Valves and Zoloto offer bronze and gun metal globe valves to IS 778, with ISI marked Class 1 models from both makers and ISI marked Class 2 models from Sant Valves and Kartar Valves offers gunmetal globe valves to IS 778 (K604, K606) and the K604-E wheel valve. For steam, the Sant Valves SBM-14 and SBM-15 union bonnet valves, rated PN 25 and conforming to IS 778 Class 2, are listed for water, oil and steam, and the Kartar Valves cast iron K-101 globe steam stop valve (15 mm to 200 mm) and K-102 junction steam stop valve (15 mm to 100 mm) are rated for steam up to 13 kg/cm2 at up to 220°C.

Next match the pressure class, choosing one that covers the highest pressure and temperature in that line. The IS 778 class sets the rating of the bronze and gun metal valves: Sant Valves body tests its Class 1 valves at 1.5 MPa and its Class 2 valves at 2.4 MPa. In the Sant Valves SBM series the standard pattern No.9 and No.5 valves are body tested at 35.15 kg/cm² and the medium pattern No.8 and No.4 at 21.09 kg/cm², and Zoloto offers medium pattern (1001, 1001A, 1003) and heavy pattern No.5 (1002) bronze globe valves. For high pressure duty, Sant Valves offers forged steel globe valves to API 602 in Class 600, 800 and 1500 from 15 mm to 40 mm, and the cast steel CS-10A to BS 1873 in Class 600 from 40 mm to 200 mm.

Then choose the pattern and ends. Straight globe valves keep the line straight, while angle valves such as the Sant Valves IS-22, the Zoloto 1001A and the Kartar Valves K-102 turn the line through a right angle. Screwed valves have threads to BS 21, IS 554 or ISO 7, the forged steel valves come with NPT or socket welded ends, and flanged valves have flanges to BS 10 Table D or F, IS 778, ASME B 16.5 Class 600 or DIN-2533 PN-16. OS&Y (outside screw and yoke) designs such as the Sant Valves IS-34 and IS-34A keep the stem thread outside the body, and Zoloto lists several of its bronze globe valves (1002, 1033, 1034) as able to be re-packed under pressure.

Kartar Valves also lists its K-103 horizontal and K-104 right angle cast iron lift check valves with this range, for non return duty on steam up to 13 kg/cm2, and a gunmetal spring loaded safety valve (K617, PN1.6, 40 mm) that opens to release excess pressure. Renewable seats and discs, found on the Sant Valves SBM union bonnet valves, the steel valves and the Kartar Valves cast iron valves, let worn parts be replaced instead of the whole valve. FPS supplies, installs and maintains globe valves across Madhya Pradesh.

Frequently asked questions

What is the difference between a globe valve and a gate valve?
A gate valve is meant to be fully open or fully shut, while a globe valve lifts a disc off a seat and can also regulate the flow. Globe valves are chosen where a line must be throttled as well as isolated.
What is a steam stop valve?
It is a globe pattern valve built for steam service. Kartar Valves offers cast iron globe and junction (right angle) steam stop valves for steam up to 13 kg/cm2 at up to 220°C, with flanged PN-16 ends.
What do IS 778 Class 1, Class 2 and Class 3 mean?
IS 778 is the Indian standard that the Sant Valves, Kartar Valves and Zoloto bronze and gun metal globe valves are made to, and the class sets the pressure rating. Sant Valves body tests its Class 1 valves at 1.5 MPa, its Class 2 valves at 2.4 MPa and its Class 3 IS-13 at 50 kg/cm², and Zoloto offers ISI marked Class 1 globe valves (1033, 1034).
When should I use an angle globe valve?
Use one where the line turns through a right angle, since the valve regulates the flow and changes direction in one fitting. Sant Valves offers the gun metal IS-22, Zoloto the bronze 1001A and Kartar Valves the cast iron K-102 junction steam stop valve.
Are globe valves used in fire protection systems?
They are used on small auxiliary lines where flow must be regulated, such as test and bypass lines, while main hydrant and sprinkler lines are usually isolated with gate, sluice or butterfly valves. FPS advises on the right valve for each line.
Does FPS supply globe valves, and how do I get a price?
FPS is an authorised distributor of Sant Valves and Kartar Valves and a dealer for Zoloto, and it supplies, installs and maintains globe valves in Bhopal and across MP. Prices depend on material, size and class and are shared on request: call or WhatsApp +91 92440 89060.
