TV-137
The EPTA® TV137 valve (FTC+FTO+Blocking) is a compact model (3 in 1) designed for industrial uses or for distribution nets where the combination of 3 valves (BLOCKING + MONITOR + ACTIVE) is necessary in a same body reducing the spaces in the skids or the regulation chambers.
The fail position depends on the desired configuration.

Variable Restrictor RV
The EPTA® RV variable restrictor is an element which makes it possible to get a higher or lower responsiveness in the outlet or regulated pressure of a self-regulating valve (for example model 1099R or VD277) whenever there is any stream variation in the pilot valve.
-
Variable Restrictor RV2
The EPTA® RV2 variable restrictor is used to have a lower or higher responsiveness in the outlet or regulated pressure of a valve (for example model VD277) whenever there is any stream variation.
-
VD277
The EPTA® VD277 fail to open (FTO) pressure regulating valve is a model designed for and in distribution networks. The operating principle is based on the pressure difference on the diaphragm provided by the regulation. It has an external regulation pilot, an external variable restrictor and a filter F250. All the elements are provided installed and interconnected.
-
VD277
The EPTA® VD277 fail open (FTO) pressure regulating valve is a model designed for distribution networks. Its performance is based in the pressure difference made by the regulation on the diaphragm. It has an external regulation pilot, an external variable restrictor and a filter F250. All the elements are installed and interconnected.

VD277SA
REGULATING DIAPHRAGM VALVE with BLOCKING SYSTEM VD277S
The EPTA® diaphragm valve with blocking system VD277S is a pressure regulator valve which is used in industries and distribution systems. The operating principle is based in the pressure difference on the diaphragm made by the regulation. It has an external regulated pilot P67S/2, an external variable restrictor RV2 and a filter F250. It has a security system with a blocking system with an independent seal.
The blocking trigger in VD277S is composed by a piston or diaphragm. The return is automatically made by the automatic relay. If it is used as a blocking active valve there is also a noise attenuator.
For the VD277SA/AR the blocking system and automatic return is commanded by two pilots (cut when high pressure and return when low pressure) which set point values are regulated. -
VG754
The EPTA® VG754 pressure regulating valve fail to open (FTO) are used whenever sensitivity, safety and high capacity in distribution networks are necessary.
Its seal is guided in cage which provides stability in big pressure drops and with capacity to control streams of either low or high levels.
