SOS
The EPTA® SOS (shut-off security) blocking valve is a positive close action valve, that is to say, normally close by the spring and kept in that position by the stream direction. The blocking trigger is formed by a piston or diaphragm and the reset is done manually. The blocking can be high cut-out, low cut-out or high cut-out and low cut-out pressure. The close of the seal is unbalanced.

OM ICR
The EPTA® OM-ICR manual operated valve is used in manual regulation as regulating blocking valve in a wide range of fluids (Gases- Liquids and Steam).
This characteristic is present in the ICR (Quick Change Inner Parts). The manual drive design “Multi-turn” allows a constant regulation together with the selected inner parts (Balanced /Unbalanced), depending on the service conditions.

9801
The EPTA® 9801 relief valve (fail close FC- fail open FO) is used mainly in gas lines as blocking or venting system depending on the configuration of the actuator and the installed peripheral elements.
This line is pneumatically operated using an actuator to diaphragm and antagonistic spring.
It has an open-close indicator and its opening time is more than a 30 seconds and their closing time is less than 1 second, it can be normally open (vent) or normally close (blocking) depending on the actuator.

Line AP1307
The EPTA® AP1307 auto-regulating valve is used in clean inviscid gases and liquids. It is used in services with temperatures up to 60ºC, in a wide range of pressure drops, where a good range of control is essential. The AP1307 is normally open in all its variants, with a balanced seal for nominal passages and unbalanced por reduced passages.
-
Line AP
The EPTA® AP pressure auto-regulating valve (auto-pilot/auto-operated) is used with a wide variety of clean inviscid gases and liquids.
The AP normally open fail with balanced or unbalanced seal, can be used in compressed air supply, flushing gas or in control panels where where it is necessary to control minimum stream intakes.

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.
