Overview

Slam Sut-off valve is installed immediately after the filter & prior to the Regulator. It normally remains open, incase the outlet pressure of the
regulator exceeds the permissible limits, the slam shut off valve senses it through the impulse line & immediately shuts off the flow to
downstream. When the regulator is repaired, the slam shut off valve is to be open manually by pulling the knob. Once the flow starts
through the slam shut off valve it will remain open till the outlet pressure of the regulator is within limits.

Overview

AMMONIA PRESSURE REGULATORS
These regulators are mainly used for ammonia gas. The trim parts for these regulators are of stainless steel. R-4108 / R 4110 I are preset
type regulators and are mainly used as second stage pressure regulation. R-2301 I is adjustable pressure regulator and is mainly used as
first stage pressure regulator. R-2402 is a fine control adjustable pressure regulator which is used when precision pressure control and is
required for instrumentation purpose like Air-Gauges. .

Overview

HIGH PRESSURE CYLINDER VALVES
These Valves conform to the Indian Standard Specifications IS:3224 (equivalent to BS:341, Part I) for Cylinder valves, in every respect.
All raw materials are fully tested for their chemical composition before being put to use. Simple construction & interchangeability of
components make maintenance and repairs easy & fast. All valve bodies are of forged construction, duly heat treated stress relieved. The
valve bodies have high strength, superior wear resistance and High impact values. We perform rigorous quality checks. Forged valve
blanks are tested from every lot for actual physical values before machining. Each valve is tested at it’s full working pressure before
despatch. All valves are soft to work because of good surface finish.
