Samson 3710 Reversing amplifier with pressure gauge double acting

E+H RIA15 process indicator Loop-powered Ex ia process indicator as field or control panel device fo
RIA15 process indicator The process indicator is available with 4 to 20 mA or with HART® protocol. In the HART® version up to 4 measured values of one sensor can be indicated in alternation. For this, the indicator can be set as a primary or secondary HART® master and actively inquire the values from the sensor. The small voltage drop of < 1V (< 1.9 V with HART®) is a huge advantage, especially in Ex-applications, where in most cases only a reduced voltage is available.
Flowserve Pneumatic Actuators - Linear - VL Series VL25 Valtek
VL Actuator Valtek VL series spring cylinder linear actuators are powerful, compact, high-performance pneumatic actuators that provide solid throttling or on-off operation for automatic control valves. The positioner supplies air to both sides of the piston, providing stiff, precise movement and high-frequency response and quick stroke speeds.
