Valve Type Selection Guide

Answer 5 questions about your application and get a specific KSB valve recommendation with model number, material, and product page link. Takes 30 seconds.

1
What is the valve function?

What does the valve need to do in your piping system?

2
What fluid are you handling?

This determines material requirements and valve suitability.

3
What is your operating temperature?

This determines material grade and seat type.

4
What pressure class do you need?

If unsure, use the P/T Rating Calculator to determine class from your operating conditions.

5
What size range?

Nominal pipe size determines whether cast or forged construction is used.

How This Valve Selection Guide Works

This tool uses a decision-tree approach to match your application requirements to a specific KSB valve model from the range supplied by Johar Engineering. The recommendation considers five key factors: function (what the valve needs to do), fluid type (material compatibility), operating temperature (material grade), pressure class (pressure containment), and nominal size (cast vs forged construction).

Valve types in our range

We supply the complete KSB industrial valve portfolio: SICCA gate valves (GTC/GTF) for full-bore isolation, SICCA globe valves (GLC/GLF) for throttling and regulation, SICCA check valves (SCC/PCF) for backflow prevention, ECOLINE ball valves (BLT-S/BLD-S/BLC-S) for quarter-turn isolation, ECOLINE butterfly valves (CDB-S) for large-bore low-pressure isolation, ECOLINE bellow seal valves (BSGT-S/BSGL-S) for zero-emission service, ECOLINE steam traps (SIB-S/SBF-S/STH-S) for condensate drainage, and MIL control valves (41000/71000/77000/76000/29000) for automated process control.

When to contact us directly

This tool provides a starting-point recommendation. For complex applications involving multiple service conditions, exotic materials (Hastelloy, Monel, Alloy 20), or automated control valve sizing with Cv calculations, contact our engineering team directly. We provide detailed valve selection support including material compatibility verification, P/T rating confirmation, actuator sizing, and complete bill-of-materials preparation from your P&ID or line list.

Valve Selection — FAQs

Gate valve vs globe valve — how do I choose?
Gate valves are for on/off isolation with full bore and low pressure drop. Globe valves are for throttling and flow regulation. If you only need to fully open or fully close the valve, use a gate valve — it has a straight-through flow path with minimal resistance. If you need to control flow rate at intermediate positions, use a globe valve — its disc-and-seat geometry is designed for stable partial-open operation. Never throttle with a gate valve; the wedge will vibrate and erode.
When should I use a ball valve instead of a gate valve?
Ball valves provide quarter-turn operation (90° from open to closed, much faster than multi-turn gate valves), better sealing with soft PTFE seats, and more compact installation. Use ball valves for quick on/off isolation, instrument root valves, compressed air, clean fluids up to 200°C, and fire-safe applications (API 607). Use gate valves for high-temperature steam (above 200°C where PTFE fails), IBR-certified boiler applications, very large sizes (above NPS 16), and where metal-to-metal Stellite seats are required for durability.
Which valve for sugar factory juice lines?
For juice and syrup lines containing fibers and suspended solids: use KSB CDB-S butterfly valves for on/off isolation and MIL 71000 V-notch ball control valves for flow regulation. The V-notch shears through fibers with a self-cleaning action. Do NOT use globe valves or cage-guided control valves, as the fibrous content will clog the trim within hours. For boiler steam mains in the same factory: use IBR-certified SICCA GTC gate valves and GLC globe valves in WCB Class 150/300.
What valve for toxic or hazardous chemicals?
Use KSB ECOLINE bellow seal valves: BSGT-S (gate) for isolation and BSGL-S (globe) for throttling. The 316 Ti metal bellows provides zero fugitive emission, with backup gland packing as a secondary seal. Available in WCB (carbon steel) and CF8M (SS 316). These are mandatory for plants subject to EPA, CPCB, or ISO 15848 fugitive emission regulations, and for fluids classified as toxic, carcinogenic, or acutely hazardous.
How do I select a steam trap?
Three types for three applications: SIB-S inverted bucket for drip legs, process heating (juice heaters, evaporators), and dirty condensate — robust, handles water hammer, continuous air venting. SBF-S ball float for heat exchangers and modulating loads — continuous immediate discharge, integral air vent. STH-S thermodynamic for high pressure (up to 170 bar), superheated steam, and compact installations — simplest mechanism with one moving part.
