Samson Control Valves: Engineering Overview and Technical Specifications

A control valve is an executive device in process automation systems (APCS), whose primary function is to modulate the parameters of the working medium flow. By changing the flow area (throttling), the valve provides high-precision control of flow rate, pressure, temperature, or liquid and gas levels in a closed technological loop.

EV Group China acts as a technological partner for the supply of Samson precision control valves, which have proven themselves as a benchmark of reliability for critically important industrial processes. These valves are designed for trouble-free operation under extreme pressures, temperatures, and aggressive media, ensuring production stability and safety.

Key engineering tasks solved by Samson valves

• Precision flow throttling: Ensuring a specified volumetric or mass flow rate of the medium (gas, steam, liquid) by modulating the position of the shut-off element.
• Pressure stabilization: Automatic maintenance of the required pressure in the pipeline (functions of a "back-pressure" or "pressure-reducing" regulator), which prevents water hammer and protects equipment.
• Process thermoregulation: Temperature control in heat exchangers and reactors through managing the flow of coolant or heating medium.
• Level control: Maintaining a specified liquid level in reservoirs, separators, and storage tanks by regulating inflow or outflow.

The design of the Samson valve is a modular system consisting of a body designed for high pressures, and an internal assembly – the trim (plug, seat). Body and trim materials, from stainless steel to exotic alloys (Hastelloy, Monel), are selected based on the chemical aggressiveness and temperature of the working medium. Control is carried out by an external actuator (pneumatic, electric), which receives signals from the APCS controller and precisely sets the plug position via a positioner.

Basic technical parameters of Samson valves

• Compliance with international standards: EN 12516, ANSI B16.34, API 609.
• Connection types: wafer, welded.
• Actuator types: pneumatic, electric.
• Fire safety design: API 607/ISO 10497.
• Configuration options: with heating jacket, various seat types (metal/metal or soft sealing).
• Leakage class: VI (according to ANSI FCI 70-2/IEC 60534-4).

Industrial application of Samson control valves

• Oil refining and petrochemicals: Control of hydrocarbon, acid, and alkali flows in reactors, rectification columns, and cracking units.
• Oil and gas industry: Regulation of flows in main pipelines, compressor stations, and gas treatment plants at high-pressure differentials.
• Energy: Control of steam and feedwater parameters in steam boiler circuits, turbines at thermal power plants, nuclear power plants, and state district power plants.
• HVAC and heating systems: Balancing and regulation of heat carrier flows in centralized and local heating and air conditioning systems.
• Water treatment and water supply: Pressure and flow control in water utility networks, at treatment facilities, and in industrial water treatment systems.
• Pharmaceutical and food industries: Precise dosing and flow regulation in sterile and hygienic processes requiring strict adherence to sanitary standards.
