API 6A Expanding Gate Valves

API 6A Expanding Gate Valves

The API 6A Expanding Gate Valves produced by RTV Ruitong Valve are suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, as well as venting systems and steam storage devices. RTV Machinery's high-performance two-way flat API 6A Slab Gate Valve is designed for critical high-pressure applications, ranging from 3000 psi to 15000 psi. It is ideal for use in wellheads, Christmas trees, and manifolds.
PFFW rising stem flat gate valve is a high-performance, bi-directional sealed concealed stem gate valve. Integral forging forming, with excellent performance in high-pressure environments, can be applied to oilfield wellheads, Christmas trees, gas trees, and manifold systems ranging from 2000psi to 20000psi.

1. The valve seat adopts an O-ring seal and a floating valve seat structure with pre tightening force applied, which makes the inlet and outlet of the flat gate valve sealed in both directions; And the opening and closing torque of this structure is only half of that of a regular valve, which can easily open and close the valve

2. When fully open, the channel is smooth and straight, with minimal flow resistance coefficient and no pressure loss. It can clean the pipeline with a capillary ball

3. Adopting a packing structure with self sealing ability, without the need for frequent adjustment, the opening and closing are extremely lightweight, and the sealing performance is reliable. There is an auxiliary sealing grease injection structure at the packing box, which is absolutely reliable in sealing performance and truly achieves zero leakage; Solved the problem of leakage at the packing of general valves

4. When the flat gate valve is closed, it can automatically remove the high pressure inside the chamber, ensuring safe use

5. Fully enclosed structure, good protective performance, and can adapt to all-weather requirements

Description

API 6A Expanding Gate Valves consists of one gate body and related gate segment. The contact surface between are designed to milled V structure.  API 6A Expanding Gate Valves are available in sizes 2-1/16 "through 4-1/16". working pressure of 2000 psi through 5000 psi.

API 6A Expanding Gate Valves are commonly used in oil and gas production, refining, and petrochemical industries. These valves are designed to provide a reliable and tight shut-off in high-pressure and high-temperature environments.

 

Features

The upper/lower roller thrust bearing minimizes operation torque;

Seats can be lubricated from grease injection fitting to reduce abrasion and promote long life;

Non-rising stem design minimize operation space
