RUSSIAN STANDARD 12X18H10T BALL VALVE
In Russia, the valves at the end of their certification are divided into two categories: valves for industrial and civil use. For all valves for industrial use (gate valves, globe valves, ball valves, butterfly valves, diaphragm valves) is requesting the certificate of conformity to the Technical Regulation n. 753 of 15/09/2009 "On the safety of machinery and equipment", which is a mandatory requirement for the manufacture and placing of same on the Russian market.
The valves for domestic use, with the exception of the valves used in domestic systems gaseous fuel (boilers, heating systems, ovens, etc..) Are not subject to mandatory certification. For valves for domestic gas demand is the declaration of conformity to the Technical Regulation n. 65 of 11/02/2010 "On safety of appliances burning gaseous fuels."
In the Russian Federation the valves according to their function are classified in the following way:
1) GOST 9697-87 R-off valves, minimum requirements;
2) GOST R 23866-87 valves with single or double seat, cage valves;
3) GOST R 27477-87 check valves (non return);
4) GOST 31294-2005 direct action safety (vent) valves.
And take that very often in the assessment of compliance so happens to certain types of valves, faucets, there are no shutters or reference standards. This is due, first, increasingly widespread use of new materials for the realization of the parts of the valve. All Russian national standards, better known as Standard Gost, were created for the valves and taps in steel or cast iron. While today for the manufacture of valves are increasingly used non-ferrous metals, plastic and composite materials.
The position of the Federal Agency on technical regulation and metrology, the question is to be applied in the mandatory certification of valves existing rules only in order to meet the minimum safety requirements, applicable to each type of valve.
