New stainless steel accessory valves expand Emerson's actuator control offering

Emerson introduces a new range of 316L stainless steel accessory valves for actuator control applications. The ASCO 800 series range includes quick exhaust valves, check valves, flow control valves (with and without integrated check valve) and pressure relief valves.

By adding these accessory valves to our existing product range, which includes switch boxes, solenoid valves, filter regulators, volume boosters and positioners, we are able to offer the complete package for valve actuator control applications. This means you can order everything from one supplier – generally as a complete engineered solution or as a product bundle. Working with one supplier enables you to make standardisation easier, which reduces your stock and saves you time and money. Initially launched in ¼" and ½"port sizes, the accessory valves are compatible with our other products and solutions, and can be used on panels and systems, such as the Actuator Control System (ACS) or a control panel for a scotch yoke actuator.

Additionally, to make standardisation easier, these accessory valves can offer you the following benefits:

• Improve plant shutdown efficiency and reliability, due to faster response times enabled by the quick exhaust valve's high capacity return flow
• Save energy by having virtually zero leakage with the check valve, due to its sealed poppet technology
• Save space, as the flow control valves with integrated check valve are fully adjustable and lockable and enable you to have 2 functions in 1 product
• Increase safety and save time and money on certification, as the pressure relief valve is already approved as a safety accessory in accordance with the Pressure Equipment Directive (PED).
