APTEK AGV4 Gauge Valves
APTEK AGV4 gauge valves isolate a pressure gauge from the measuring point and provide a bleed screw for controlled venting after isolation. The forged body uses a union-bonnet construction and a G 1/2 swivel female gauge outlet for positioning the instrument.
Construction and Technical Data
- Manufacturer and series: APTEK AGV4.
- Connection versions presented by ALFACOM: G12 and N12; confirm the inlet thread when ordering.
- ALFACOM product options include 316 stainless steel and carbon steel bodies.
- Maximum working pressure stated in the datasheet: 413 bar / 6000 PSI at 100°C.
- Gland-packing options: PTFE or graphite, according to configuration.
- Design stated as in accordance with DIN 16270.
- Catalogue weight: 0.50 kg.
For higher-temperature applications, refer to the manufacturer's pressure-temperature chart. Confirm the selected body's material, packing and end connections against the actual medium and operating conditions.
Specify the Required Version
Provide G12 or N12, body material, the connections at both ends, medium, operating pressure and temperature, installation clearance and quantity. Availability and lead time are confirmed for the requested version.
Isolation and Maintenance
Gauge removal and venting must follow the plant's isolation and controlled depressurization procedures and be performed by qualified personnel. The gauge valve provides isolation and venting; any required overpressure protection is selected separately.
Does the pressure rating establish suitability for steam?
No. Check the complete valve configuration, packing, connections and pressure-temperature limits for the actual duty.
