■ Product Overview
The clamp type check valve is suitable for nominal pressures ranging from PN1.0 MPa to 420 MPa Classl50~2500; On various pipelines with a nominal diameter of DN15-1200mm and NPsl/2-48 operating temperature of 196-540 ℃, measures should be taken to prevent medium cross flow. By selecting different materials, it can be suitable for various media such as water, steam, oil, nitric acid, strong oxidizing media, and urea.
