In this how-to video, we’ll assemble a 2″ SAMSON 3241 globe valve and prepare for actuator mounting.
Lloyds Registry EMEA has confirmed the air consumption rates of Spirax Sarco’s SP400 and SP500, making them the world’s most energy efficient digital electro-pneumatic valve positioners. This recognition of the SP400 and SP500 electro-pneumatic smart positioner range — developed in-house
Discover the flexible all-round positioner for linear and rotary actuators in a slightly different way! The ultimate package: easy mounting, fast initialization, modular setup, enhanced diagnostics, Partial Stroke Test, and, extremely low air consumption – make the SIPART PS2 one
Do you know the principal function of a Safety Valve?
This manual on control valve sizing brings together the mathematical tools required to select Durco valves properly for control valve applications. The equations presented for liquids, gases, and steam are based on the ISA standard S75.01 and are divided into
ESD/ESV valves are the final defence against process misreactions. These valves have a function which requires much more reliable performance than standard remotely operated on-off valves. Still today ESD valves are ranked often as ordinary shut-off valves in specifications. Valves
Masoneilan Control Valves The Masoneilan 20000 Series sigle-ported, globe type valves are designed to cover a wide range of applications. Their versatility makes them well suited for large capacity requirements, for the higher process pressures often encountered, and equally capable
Masoneilan Camflex II The Masoneilan Camflex 2 control valve is based on an elegant design – one which is uncomplicated yet attentive to all the right details. Designed as an integrated system of valve, actuator and positioner, the Camflex

The effects of exceeding safe pressure levels in an unprotected pressure vessel or system, can have catastrophic effects on both plant and personnel. Safety relief valves should be used to protect any pressurised system from the effects of exceeding its
The primary purpose of a pressure or vacuum relief valve is to protect life and property by venting process fluid from an overpressurized vessel or adding fluid (such as air) to prevent formation of a vacuum strong enough to cause
The purpose of a pretest is to determine if a Pressure Relief Valve (PRV) would have operated on demand within the set pressure tolerance limits of the code for the entire period it was in service. What are pretest test
