Lock Type Fully Welded Ball Valve

The Lock Type Fully Welded Ball Valve produced by RTV Ruitong Valve have uneven stress distribution due to the same material as the pipeline. They will not deform due to earthquakes or vehicles passing through the ground, and the pipeline is resistant to aging. The sealing ring body is made of PTFE material with a content of 20% C (carbon), ensuring complete leakage free (0%). It has the advantages of maintenance free, no leakage, strong reliability, high safety, and long service life.

Full welded ball valve, full bore welded ball valve Purpose:

1: Urban gas: gas output pipelines, main and branch supply pipelines, etc.

2: Centralized heating: Large scale heating equipment output pipelines, main pipelines, and branch pipelines.

3: Heat exchanger: opening and closing of pipelines and various circuits.

4: Steel plant: various fluid pipelines, waste gas selective discharge pipelines, gas and heat supply pipelines, fuel supply pipelines.

5: Various industrial equipment, various heat treatment pipelines, various industrial gas and heat pipelines.

Standard specifications for fully welded ball valves and full bore welded ball valves:

Size: DN15~1500

Pressure rating: ANSI 150lb~2500lb

Applicable temperature: -35~350 ℃

Valve body material: carbon steel, stainless steel, alloy steel

Internal material: carbon steel, stainless steel, alloy steel, special materials

Features of fully welded ball valve products:

The valve is full bore and has a fixed pivot structure.

The valve seat and valve stem are sealed twice, and the valve seat has an independent grease injection port.

Fixed ball cutoff and release function, equipped with dual piston effect valve seat, zero leakage.

The valve body adopts a fully welded type, which can extend the valve stem and be used underground.

Anti static, fire safe, and valve stem anti blowing function.

Long service life.

It is welded by forged steel. The forging materials are subjected to ultrasonic examination according to ASME nondestructive flaw detection requirements. The welding slope on the connection face is subjected to liquid penetration examination.

Corrosion Resistance And Sulfide Stress Resistance
Certain corrosion allowance is left for the body wall thickness. The carbon steel stem, fixed shaft, ball, seat and seat ring are subjected to chemical nickel plating according to ASTM B733 and B656. In addition, various corrosion resistance materials are available for users to select. According to customer requirements, the valve materials can be selected according to NACE MR 0175/ISO 15156 or NACE MR 0103, and strict quality control and quality inspection should be carried out during the manufacturing so as to fully meet the requirements in the standards and meet the service conditions in sulfurization environment.

Welding Of Transition Pipe
During the manufacturing of the fully welded pipeline ball valve, the transition pipe can e welded for the welding ends valve. The transition pipe can be supplied by users or by our company according to user requirements. Please indicate the transition pipe diameter and length A when placing orders.

Product Overview

The fully welded locking ball valve has a locking function, which can control the on/off of heating and water supply systems for each household and group, and cannot be opened non destructively, achieving effective control. Suitable for urban media pipelines, large-scale heating equipment pipelines, various fluids in steel mills, gas heat supply, fuel supply pipelines, etc.

Structural Features

The fully welded locking ball valve consists of a valve body, valve core, valve stem, and locking mechanism. The locking mechanism is a valve stem connected to the valve core in the valve body locking hole. Install springs, claws, and ratchet locking caps on the valve stem joint. After adjusting the valve core position, tighten the ratchet locking cap, and the user cannot open it on their own.

The fully welded locking ball valve is assembled and welded as a whole, avoiding any possible leakage of media. It adopts a spring loaded valve seat combination structure, which has strong adaptability to pressure and temperature changes, ensuring close contact between the sealing ring and the ball. On the premise of ensuring sealing, the valve door can be opened and closed flexibly and operated easily.
