FAQ

Q: What is the difference between interface size and actual flow bore size for pneumatic cylinders and valves?
A: Interface size (such as G1/8, G1/4, G3/8) refers to the threaded connection dimension, which is not equal to the actual flow bore size that determines the medium flow capacity.
Q: Which material is suitable for pneumatic cylinders used in pharmaceutical sterile environments?
A: 316L stainless steel is recommended, paired with PTFE seals to meet CIP/SIP cleaning requirements and food-grade hygiene standards.
Q: Can non-standard solenoid valves be matched with stainless steel cylinders?
A: Yes, Ningbo Dongchao Automatic Control Equipment Co., Ltd. provides matching 316L stainless steel solenoid valves with PTFE/FKM seals for complete sets adapted to pharmaceutical, food and chemical scenarios.
