Product introduction

H42b ammonia check valve uses the fluid pressure difference and its own weight to realize the lifting and lowering of the valve disc. It is applicable to most horizontal pipelines in the tank, automatically preventing the reverse flow of the medium and protecting the upstream equipment. It is suitable for clean media, not for media containing solid particles and high viscosity.
