Product catalog summary

Specifications:
The document describes a 3-way high flow-rate valve available in sizes 1"1/4, 2", 3", and 4" with a pressure rating of PN16. The valve features F/F gas pipe threads conforming to ISO228 standards. It is equipped with a double-acting (DA) actuator and operates within an ambient temperature range of 0 to +60°C, with a maximum temperature of +100°C. The pilot pressure ranges from a minimum of 4.0 bar to a maximum of 8.0 bar. The valve body is made of bronze, with various components such as the spacer for the cylinder, seal holder, piston, and cylinder made from anodized aluminum. The piston rod is constructed from stainless steel AISI 304, and the rod wiper is made of PTFE. Internal o-rings and shutter seals are made from FKM for sizes 1"1/4 to 2", and NBR for sizes 3" to 4".

Optional Features:
The valve can be optionally equipped with ATEX certification, a switch box with 2 reed sensors, and shutter seals made from PTFE or EPDM. It can also function in vacuum/vacuum breaker mode with vacuum pumps and as a diverter with blowers. The cylinder is swiveling with four possible positions.

Operation Chart:
The operation chart provides dimensions and flow coefficients (Kv) for each valve size. The Kv value represents the volume flow rate of water through the valve under specific conditions (ΔP = 1 bar; T = 5-40°C; density = 1000 kg/m³). The chart includes measurements for gas pipe thread, DN, and various dimensions (A, B, C, D, E, F, H) in millimeters, along with the minimum absolute pressure in mbar and the Kv value in m³/h.

Applications:
The valve is suitable for use with vacuum pumps and blowers, providing functionality in both vacuum and diverter modes.
