Product catalog summary

Overview: The document provides technical specifications and operational details for a multi-function auto-control valve and a pressure relief valve. These components are designed for fluid and air applications, offering versatility in various pressure conditions.

Specifications:

The controller is directly fixed to the valve, reducing damage during transport and allowing for quick installation.
The valve body is compatible with all types of controllers without requiring technical conversion, suitable for both low and high-pressure applications in vertical and horizontal positions.
Constructed with a straight flow path to minimize malfunctions from impure water and reduce turbulence.
Materials used include Cast Iron, Ductile Iron, Bronze, and Stainless Steel, ensuring durability and compatibility with international standards.

Valve Body Design:

Features a cylinder design for the valve body structure.
Small, lightweight, and easy to install with a simple and elegant appearance.
Functional through an inlet-guiding hole that manages pressure to control the valve's opening and closing.

Pressure Relief Valve:

Installed on the outlet pipe of water supply pipelines to maintain safe pressure levels and prevent damage from pressure surges.
Automatically opens to release excess pressure and closes slowly when pressure normalizes.
Pressure adjusting range is 0.3 to 4 kgf/cm², with special orders available for higher ranges.

Materials and Construction:

Components include cylinder bolts, O-rings, springs, pistons, and sealing elements made from materials like NBR, Bronze, and SS304.
Available in various sizes with flange and thread end options, supporting a wide range of working and test pressures.

Operational Parameters:

Applied temperature range is -15°C to 80°C.
Pressure relief valve working pressure should be greater than 0.3 kgf/cm², with full gate opening at 1.5 kgf/cm².

Catalog excerpts

MULTI-FUNCTION AUTO-CONTROL VALVE � Controller is fixed directly and designed of non-controller conduit. It reduces the damage of the controller conduit while transporting the equipment. � Controller is designed to be quickly screw fastened, enabling fast and easy installation. � The valve body can match with all types of controller without technical conversion, and all kinds of control valves can be formed. � Cylinder design is adopted for the valve body structure, making the valve applicable to low and high pressure in both vertical and horizontal positions. � Straight flow path is designed inside valve body. The large flow can reduce the malfunctions caused by impure water and effectively decrease turbulence and related bad effects. � The valve body is shaped and formed as whole. Small volume, lightweight, and easy installation. Simple and elegant appearance. � Professional manufacturers, best quality, and reasonable price.

Materials of valve body: Cast Iron, Ductile Iron, Bronze & Stainless Steel The valve body of main valve becomes functional by an inlet-guiding hole. This hole transfers pressure to pressure chamber. When enough pressure accumulates in the pressure chamber, it generates pushing force that makes the piston close to valve seat and generates the closing motion. There is another outlet guiding hole inside the pressure chamber. When the hole is open, pressure in pressure chamber dissipates and valve gate is pushed open by incoming water pressure.
