The Hongsen KM Diaphragm Hand Valve is a manually operated stop valve designed for refrigeration, cold storage, and air conditioning systems. It can be installed on liquid, suction, and hot gas lines to provide convenient manual control of refrigerant flow during system operation and servicing.

The valve uses a dual stainless steel diaphragm design for reliable sealing and features an elastic valve port seal for smooth closing. Its protective bonnet helps reduce exposure to water and dust, while the valve stem allows the opening position to be adjusted quickly between fully open and half open.

Features

• The hand valve has two stainless steel diaphragms that help prevent leakage throughout its service life.
• The valve port features an elastic seal, allowing the hand valve to close with a gentle twist.
• The valve bonnet has a protective design that helps protect the hand valve from water and dust.
• The hand valve can be adjusted to fully open or half open by rotating the valve stem one and a half times.
• Designed for use in refrigeration, cold storage, and air conditioning systems.
• Suitable for installation on liquid, suction, and hot gas pipes.
• Available with threaded SAE and welded ODF connection options for different refrigeration piping requirements.
• A mounting hole allows convenient installation on an instrument panel.
