Industrial gas valves for pressure regulators non return slam shut off safety relief

INDUSTRIAL GAS VALVES

WE ALSO INSTALL INDUSTRIAL GAS MANIFOLDS, COPPER PIGTAILS, REGULATORS, VALVES AND RELATED EQUIPMENT

Slam Shut-Off Valve

Slam Shut-off valve is installed immediately after the filter & prior to the Regulator. It normally remains open, incase the outlet pressure of the regulator exceeds the permissible limits, the slam shut off the valve senses it through the impulse line & immediately shuts off the flow to the downstream. When the regulator is repaired, the slam shut off is to be open manually by pulling the knob. Once the flow starts through the shut off valve it will remain open till the outlet pressure of the regulator is within limits.

Non-Return Valve

We are manufacturing two types of Non-Return valve. V-6301 is having metal to metal seat and is suitable for high pressure applications up to 200Kg/ V-6304 is having soft seat, It is suitable for maximum working pressure of 20kg/. we can supply non return Valves for all gases. The material of construction depends on the nature of media/gas for which it is to be used.

Flame Arrestors

Flame arrestors are used to arrest the flame from reaching the highly dense area of fuel, incase of backfire & thus avoids accidents & explosions. When a flammable gas escapes through the safety relief valve to atmosphere it must pass through the flame arrestor which will prevent the occurrence of accidents/backfire

VALVES : High Pressure Cylinder Valves

These valves conform to the Indian standard specifications IS:3224 (equivalent to BS:341, Part I) for Cylinder valves in every respect.
All raw materials are fully tested for their chemical composition before being put to use. Simple construction & interchangeability of components make maintenance and repairs easy & fast. All valve bodies are of forged construction duly Heat treated / Stress relieved. The valve bodies have High strength, Superior wear resistance and High impact values.
Rigorous Quality checks. Forged valve blanks are tested from every lot for actual physical values before machining. Each valve is tested at it's full working pressure before dispatch. All valves are soft to work because of good surface finish.
