Low-temperature shut-off valve working principle: Materials working at low temperature should ensure its low-temperature performance, mainly to ensure its cold shock strength. The trim must be properly selected to have sufficient cold impact strength to prevent fracture. C and Cr alloy steels quickly lose their impact strength at temperatures below -20 ° C, so the use temperature is limited to -30 ° C and ..
