Mark 2000 Series Angle Seat On/Off Control Valves

Product catalog summary

Overview: The Mark 2000 Series is an externally piloted angle-seat on/off control valve designed for high flow rates and compact applications. It features a stainless steel body and trim for corrosion resistance, making it suitable for various media including steam, water, air, chemicals, and process gases.

Key Features:

360° actuator rotation and fast response.
Maintenance-free actuator with a long service life.
Self-adjusting packing glands and low air consumption.
Water-hammer free design and compact space-saving actuator.
Standard position indicator and optional solenoid available.

Applications: The valve is used in industries such as dyeing, washing, automotive, brewing, aerospace, and more, particularly where space is limited.

Specifications:

Sizes range from 1/2" (DN15) to 2" (DN50).
Body Material: 316 Stainless Steel; Trim Material: 304 Stainless Steel.
End Connection: NPT with other options available upon consultation.
Seat Material: PTFE; Packing Material: Spring-loaded PTFE V-Rings.
Actuator Housing: Nickel-plated brass (50 mm) or Aluminum (80 mm).
Actuator Supply Pressure: 29 - 145 psi (2 - 10 bar).
Temperature Range: -40° to +397°F (-40°C to +200°C).

Configurations:

NCA (Normally Closed Against Flow) for liquid and gas services to prevent water hammer.
NCW (Normally Closed With Flow) primarily for gas services.

Ordering Information: The ordering schematic includes model, series, size, material, actuator material and size, and function (NCA or NCW).

Solenoid Options: Available in 125VAC or 24VDC for 50mm or 80mm actuators, with specific model numbers for different sizes and voltages.

Dimensions and Weight: Detailed dimensions and weights are provided for each valve size in both inches and metric units.

The angle-seat construction of the body makes possible extremely high flow rates, particularly in comparison to conventional globe valves. The compact size and light weight design makes this valve ideal for OEM machinery and other applications where space is at a premium. All trim components and body are stainless steel for maximum corrosion resistance. However, the MK2000 is economical enough to use on general utility services as well. Whether steam, water, air or chemicals and process gases, the Mark 2000 provides unparalleled flexibility for on/off service.

Mark 2000 Series Angle Seat On/Off Control Valves-2

Mark 2000 Angle-Seat Valves Specifications -2- Description: In the "NCA" configuration, the medium enters the MK2000 under the seat such that the valve closes against the pressure of the flow. This 'closing against the flow' eliminates water hammer damage associated with liquid service (or condensate hammer in steam lines), but is also ideally suited for gas service as well. The "NCW" configuration 'closes with flow' and is primarily used on gas service. This option is used more frequently in larger valves as the pressure drop capability in the "NCA" configuration lowers. • The Mark 2000 is normally...
