Safety shut-off valves are designed to protect gas installations from over pressure or too low pressure (or gas shortage), ie. they activated in case of increase (or decrease) of pressure in relation to the permitted value. They have protection against rupture of the membrane. They are installed in front of gas pressure regulator. For safety reasons, safety shut-off valve type:610-SPV can be deactivated only manualy.

Temperature operating range: -10° ÷ +60°C.

Safety shut-off valve type 690, 690-K is intended to protect the closed systems for natural gas preheating, oil and other energy-related and technical fluids, which are under higher pressure than the pressure in the installation of the heating fluid.
For safety reasons, safety shut-off valve type:690.690-K can be deactivated only manualy.

Temperature operating range is (-10 ÷ +110)° C, and on special request it can be (-60 ÷ + 110) °C.

Excess flow valve is used in pipeline installations and plants, gas lines, as well as for installation on pressure vessels, in order to prevent the flow of fluid from overflowing. The common use is for the installations for propane-butane, with maximum operating pressure 16.7 bar. It is made in variants A and B (for DN15 ÷ DN250) and variants C (for DN25 ÷ DN125). All three variants are partially ratified by construction and serve for the same purpose but adapted for different types of installation.
