Kofloc Model 6700 Series Pressure Regulating Valve

Description

The pressure regulating valve controls the pressure applied to the flow to keep it constant or reduce the pressure during flow control. Pressure regulating valve are classified into reducing valves and back-pressure valves. Reducing valves make the outlet-side pressure constant when the pressure on the inlet side changes, and are used at the first stage of systems in general. Meanwhile, back-pressure valves are a kind of constant-volume relief valve that remove gas while keeping the primary-side pressure constant.

This regulating valve is a larger version of our 6600 regulator. The design is compact, yet it permits quick, reliable, high-accuracy pressure regulation in a large flow range.

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.

Features

Compact regulating valve for large flow
The compact, lightweight valve has excellent control characteristics in a large flow range, ensuring the repeatability of ±1% when the primary and secondary pressure change.
Complete fluid shutoff
When the secondary pressure is set at 0, it functions also as a stop valve.
Ideal for in-line mounting
The fluid inlet and outlet are provided on the sides of the body, permitting, easy in-line piping.
Non-bleed type
This non-bleed type valve has passed stringent leak tests, thus eliminating concerns.
