Product catalog summary

Specifications:
The document details a double-acting pneumatic actuator designed for use with vacuum pumps and blowers. It is a 2-way high-flowrate valve available in sizes 1"1/4, 2", 3", and 4" with a pressure rating of PN16. The valve body is made of bronze, and various components are constructed from anodized aluminum, brass, stainless steel, and technopolymer. The actuator operates within an ambient temperature range of 0 to +60°C and can withstand a maximum temperature of +100°C. The pilot pressure ranges from 4.0 to 8.0 bar, and the maximum negative pressure is -995 mBar.

Procedures:
The datasheet provides information on the pilot pressure required for different valve sizes and the corresponding flow coefficients (Kv) for various pressure differentials (Δp). It also includes dimensions for each valve size, detailing measurements such as diameter and length.

Standards and Certifications:
The valve can be optionally certified with ATEX certification. Additional options include a 2-reed sensor limit switch-box and shutter seals made of PTFE or EPDM.

Recommendations:
For specific applications or configurations, it is recommended to contact Maros Engineering’s Technical Department for further assistance.

Key Data from Tables:
The tables provide detailed specifications for each valve size, including the gas pipe thread size, diameter (DN), maximum pressure differential (Δp max), and flow coefficient (Kv). The flow coefficient Kv indicates the volume flow rate of water through the valve under specified conditions.
