2、 Detailed information

Product Overview

The slab gate valve is a parallel single gate structure, with a welded shell and a bolted connection between the valve body and valve cover. It has the characteristics of full-bore design, online maintenance, self-cleaning of the valve seat sealing surface, low torque, and no need for daily maintenance. It plays a role in guiding/cutting off pipelines and is suitable for media such as oil, gas, and water. It is widely used in natural gas, petroleum, chemical pipelines, and pipeline pump station outlets.

The design and inspection can comply with standards such as API 6D, GB/T 19672, JB/T 5298, API 598, GB/T 26480, etc. The fire safety meets the requirements of API 6FA and has passed test certification. NACE anti-corrosion and acid resistance are optional, and ISO 15848 low leakage is optional.
