GAS Cylinder valve protection system

           VALVE PROTECTION SYSTEM

       General

Valve bodies are made of brass alloy and can get damaged, if it is hit against any object.  This may develop leak of LPG creating serious hazards. To prevent this, protection for the valve is provided by means of valve protection ring assembly on the top of the cylinder.

     Safety Cap

Valve outlet is fitted with safety cap manufactured out of Delrin Dupont 500 material to avoid damage to internals of the LPG valve and also to arrest the entry of dust particles and dirt inside the valve assembly. Safety cap  should  be put on to the valve at all times except for filling of the cylinder at the  plant and usage of the cylinder at the customer’s premises.  If the safety cap is not fitted on to the valve, valve may get damaged due to entry of dust particles or dirt into the valve and may cause leakage of LPG through the valve.  Hence, the safety cap is also considered as a protection for the leakage of the valve.  Safety cap can withstand  a  maximum working pressure of 2.45 M Pa of LPG and as such safety cap is very useful to stop the leakage from the valve, in case there is any leak through the valve seat. 

      ULTRAS0NIC VALVE CLEANING EQUIPMENT

   Each and every valve housing after machining are being cleaned by  the valve  manufacturers with Utrasonic Cleaning Euipment to remove any oil, grease, chips from the valve housing before assembly.  The solution used in Ultrasonic Cleaning Equipment is Trichloroethylene.  In this system, there are three chambers.  The first chamber contains liquid trichloroethylene which vibrates at ultrasonic frequency. The second chamber is of liquid trichloroethylene without any frequency and the third chamber is a vapour chamber.
