I. Product Introduction

This drain valve is available in two, three, and four-chamber structures, respectively suitable for gas pipelines with pressures below 15,000 Pa, 25,000 Pa, and 35,000 Pa, effectively removing condensate from the pipelines.

II. Structural Features

This drainage valve does not have a fixed water pipe; it employs a method of regular water supply checks at the observation hole. During a single startup filling, the 1" pipe cap on the top cover must be opened to release air.

Insert steam heater into the open room, determine whether external steam is needed based on weather conditions; cover the 1" pipe cap if steam pipe is not connected.
