ALFAMATIC CW SVT Sampling Tap
Threaded sampling tap with a hexagonal bar body, for taking a controlled sample from a process line.
Specify the sample connection, fluid and service conditions. Check the wetted materials and sealing arrangement in the model document and allow safe access at the sampling point.
ALFAMATIC CW YSP-I Y-Strainer
Threaded Y-strainer with an investment-cast body, removable screen and drain plug, for protecting downstream equipment from carried solids.
Specify the required screen opening, flow rate, allowable pressure loss and cleaning access. The catalogue lists an optional 80-mesh screen; confirm the screen supplied for the selected unit.
ALFAMATIC CW SV Sampling Valve
Threaded sampling valve with an investment-cast body for drawing a sample from process pipework.
Select the size, thread standard and wetted materials for the actual fluid and operating conditions. Define the sampling procedure and any flushing or cleaning requirements before installation.
ALFAMATIC CW CV-21 Spring Check Valve
Two-piece threaded check valve with a spring-assisted closing mechanism to prevent reverse flow.
The catalogue distinguishes pressure ratings by size and lists hard and soft sealing alternatives. Confirm the exact size and seat configuration, installation orientation and opening differential for the application.
ALFAMATIC CW CV-S Swing Check Valve
Threaded swing check valve with an investment-cast body and a hinged disc that opens with forward flow.
Check the permitted installation orientation, minimum operating flow and closure behaviour for the pipeline. Match the thread standard, materials and service conditions to the selected valve.
ALFAMATIC CW CVWD Wafer Check Valve
Compact wafer check valve for installation between pipe flanges. The catalogue identifies cast stainless steel body options and DIN 3202-K4 face-to-face dimensions.
Check the flange interface, available disc travel, installation direction and clearances to adjacent equipment. Confirm the actual body grade and sealing arrangement for the selected unit.
Threaded Stainless Steel Needle Valve
Needle valve for fine manual adjustment or isolation of a small flow. The linked drawing lists an F316L body and stem with PTFE stem packing.
Select the size and thread interface using the drawing. Verify allowable operating pressure and temperature for the actual fluid and service; shell and packing test pressures are not operating ratings.
ALFAMATIC CW GAV Threaded Gate Valve
Investment-cast gate valve with a rising stem and female threaded ends, intended primarily for open or closed isolation service.
Match the thread standard and wetted materials to the pipework and fluid. Allow clearance above the valve for the rising stem and confirm the model-specific operating limits.
ALFAMATIC CW GLV Threaded Globe Valve
Investment-cast globe valve with a rising stem and female threaded ends, for manual isolation or flow adjustment where the selected configuration is suitable.
Confirm flow direction, pressure drop, sealing materials and service conditions. For a flow-control duty, provide the required flow range and differential pressure for selection.
