For any steam service safety valve installation in India, IBR certification is not optional — it is a legal requirement under the Boilers Act 1923 and IBR 1950. Krishna Industries sources angle type safety valves exclusively from IBR-approved vendors and supplies IBR Form C certificates with every steam service safety valve order. Confirm steam service at order stage to ensure IBR-certified supply is arranged.

IBR Compliance — Why It Is Mandatory for Steam Safety Valves in India

The Indian Boiler Regulations (IBR) 1950, framed under the Boilers Act 1923, are the statutory framework governing the design, manufacture, inspection, and operation of steam boilers and steam vessels in India. Every boiler inspector (the authority issuing the Boiler Safety and Fitness Certificate — BSFC) verifies IBR compliance of all boiler fittings including safety valves at every annual inspection.

Angle Type vs Straight Pattern Safety Valve — Which to Specify

Set Pressure Range and Body Material Selection

How Set Pressure Works — Buyer Guide

Set pressure is the inlet pressure at which the safety valve opens and begins to discharge. It is factory-set by compressing the spring to a calculated load that corresponds to the required set pressure — this is not a field-adjustable parameter for routine maintenance. Understanding set pressure, blowdown, and accumulation is essential for specifying the correct safety valve.

Technical Specifications

Applications in Indian Industries

• Packaged steam boilers — Indian textile, food, pharma, chemical plants — CS WCB IBR-certified angle type safety valve DN25–DN50 screwed BSP — set pressure 10–17 bar (typical Indian packaged boiler range) — two safety valves per boiler as required by IBR Regulation 294 — IBR Form C supplied — horizontal outlet for compact boiler house discharge piping — Indian packaged boiler manufacturers (Thermax, Forbes Marshall, Cheema Boilers specification equivalent) — Gujarat, Maharashtra, Tamil Nadu industrial boiler installations
• Compressed air receivers and systems — CI screwed BSP DN15–DN25 — set pressure 7–10 bar — compressor receiver overpressure protection — non-IBR service — most Indian factory compressed air systems: 7 bar working pressure, safety valve set at 8–8.5 bar — CI body economical for this low pressure non-corrosive service — replace when relief event is observed (disc wear after repeated relief events)
• Steam distribution headers and process steam vessels — CS WCB flanged DN50–DN100 — set pressure 10–25 bar — IBR Form C supplied — steam header overpressure protection, autoclave safety relief, jacketed vessel steam space protection, pharmaceutical steriliser steam safety — flanged body for larger discharge capacity requirements at medium pressure steam service
• Chemical plant pressure vessels — Ankleshwar, Vapi, Dahej GIDC — SS304 or CS body — screwed or flanged — non-steam chemical service: reactor overpressure protection, storage vessel pressure relief, process vessel safety — non-IBR for non-steam chemical service — IS 3224 or API 526 as applicable — SS body for corrosive chemical environment
• Water treatment and hydraulic systems — CI screwed BSP DN15–DN25 — set pressure 5–10 bar — pump discharge overpressure protection, pressure vessel relief on water treatment pressure filters, hydraulic power pack relief — non-IBR service — simple CI body safety valve for clean water and hydraulic oil pressure protection

• WCB Globe Valve — install upstream of safety valve on steam lines where isolation for safety valve testing and replacement is required — globe valve is the correct upstream isolation valve (not ball valve, which has no throttling ability for controlled depressurisation)
• Single Plate Wafer Check Valve — pump discharge NRV in the same steam condensate return and boiler feed water systems where safety valves protect the steam side
• Y Strainer — install upstream of safety valve on steam lines — removes scale and particulates that prevent disc from reseating cleanly — a leading cause of safety valve weeping in Indian steam systems is scale on the disc seat preventing full closure
• Stud Bolts — ASTM A193 B7 — for flanged end safety valve installation — A193 B7 / A194 2H standard fastener for Class 150+ flanged joints on steam systems

Frequently Asked Questions

1. Why is IBR certification mandatory for steam safety valves and what is IBR Form C?

The Indian Boiler Regulations (IBR) 1950 are statutory regulations under the Boilers Act 1923 that govern all steam boilers in India above 1 kg/cm² steam pressure. IBR Regulations 294–297 require that every boiler be fitted with at least two safety valves of IBR-approved design. IBR Form C is the statutory certificate issued for IBR-approved boiler fittings — it confirms that the specific safety valve design has been tested and approved by the IBR authority. A boiler inspector (the authority issuing the Boiler Safety and Fitness Certificate) checks for IBR Form C on all safety valves at every annual boiler inspection. Without Form C, the safety valve is not considered IBR compliant regardless of its physical quality — the boiler fitness certificate will not be issued, the boiler cannot operate legally, and the operator’s insurance on the boiler is void.

2. Can I adjust the set pressure of a safety valve after installation?

Not without proper certification and re-sealing. The set pressure is factory-set by compressing the spring to a calibrated load and the adjusting mechanism is sealed with a lead wire and tamper-evident cap as required by IBR. Breaking this seal to adjust set pressure in the field is a regulatory violation for IBR boilers — it voids the IBR Form C compliance of the valve. If set pressure adjustment is required — for example, because operating pressure has changed — the valve must be removed, sent to a certified workshop for re-setting and re-testing, a new set pressure test certificate issued, and the tamper seal re-applied. For IBR boilers, the adjusted valve must be re-certified to IBR Form C before reinstallation. Ordering a new valve at the correct set pressure is often faster and more economical than the re-certification process for standard packaged boiler safety valves.

3. How many safety valves does my boiler need?

IBR Regulation 294 requires a minimum of two safety valves on every registered steam boiler. The two valves may be set at slightly different pressures — typically one at operating pressure and one slightly higher — so that the first valve handles minor pressure excursions and the second provides full protection at maximum allowable pressure. Both valves must be IBR-certified with IBR Form C. For large boilers or high-pressure steam drums with large steam generation capacity, multiple safety valves may be required to provide sufficient total relieving capacity — this is calculated from the boiler’s maximum continuous rating (MCR) in kg/hr of steam at the set pressure.

4. My safety valve is weeping (leaking slightly when closed) — what causes this?

Weeping from a closed safety valve in Indian steam systems is almost always caused by one of three conditions: scale or particulate matter on the disc seat preventing full closure (most common — install a Y strainer upstream), disc or seat erosion from repeated relief events (disc and seat require lapping or replacement), or set pressure too close to operating pressure (blowdown insufficient — operating pressure creeps above reseat pressure during normal operation). For IBR boilers, a weeping safety valve must be attended to promptly — continuous weeping erodes the disc and seat progressively, eventually preventing the valve from opening fully at set pressure, which is a safety failure. Do not attempt to hold a weeping safety valve closed with additional weight or mechanical restraint — this is a serious safety violation and a common cause of boiler accidents.

5. What information do I need to provide when ordering?

For steam service (IBR): operating pressure (bar g), required set pressure (bar g), steam condition (saturated / superheated — if superheated, provide steam temperature), boiler MCR (kg/hr) if sizing for full boiler protection, connection size (DN and screwed or flanged), body material preference (CS standard for steam service). For compressed air: operating pressure, set pressure, connection size. For chemical / process: media, operating pressure, set pressure, temperature, connection size, body material.
