Internal Thread Pneumatic Angle Seat Valve - Overview, Applications, Principle, Features & Technical Parameters

The internal thread pneumatic angle seat valve mainly adopts various specifications of threaded connections, which is easy to install and disassemble. It is suitable for small and medium-sized pipeline systems.

Applications

Controlled Gases: Neutral gas, air

Controlled Liquids: Automatic industrial control fluid, food-grade dairy industry, domestic water, ordinary pipeline media, etc. The angle seat valve is widely used for frequent starting in a short time, featuring sensitive response and accurate action.

Working Principle

The angle seat valve can save space while maintaining flow rate. It adopts a guided angle seat valve operated by a single-acting pneumatic actuator with spring safety protection. During use, normally open or normally closed type should be selected. The product is made of stainless steel casting and polytetrafluoroethylene, which can be used in most gases, liquids, steam and corrosive occasions. It is equipped with a radiator to protect the actuator and ensure a long service life of the valve.

Features

1. Equipped with valve open or closed position display.

2. External pneumatic pilot, which can extend service life and realize maintenance-free operation.

3. There is a self-adjusting sealing gland between the overflow port and the sliding block, which can improve the sealing performance.

4. The valve body adopts an angle seat structure, which can achieve large flow rate (especially compared with ordinary globe valves), with compact structure and fast response.

Standard Design

1. Single-acting (pneumatic head usually has one port); Working principle: It achieves opening and closing through spring return, divided into normally open type and normally closed type.

2. Double-acting (pneumatic head usually has two ports); Working principle: It is controlled to open and close by air supply. (According to customer requirements, double-acting with spring return can also be selected for more precise control.)

According to the pipeline installation type, pneumatic angle seat valves can be divided into: Welded connection, Quick-install connection, Threaded connection, Flanged connection

According to the type of actuator, pneumatic angle seat valves can be divided into: Plastic actuator angle seat valve, Stainless steel actuator angle seat valve
