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.

The Hongsen Nitrogen Testing Pressure Gauge – HS-NG is designed for monitoring pressure during refrigeration system leak testing, nitrogen charging, and piping maintenance. It provides technicians with a clear pressure indication when testing different refrigerant systems and when using nitrogen for cleaning and protecting welded refrigeration pipes.

Its compact ball valve allows easy and precise pressure control, while different connector options provide flexibility for various system and service requirements. The red pointer can also be used to mark and retain the input pressure, making it easier to monitor pressure changes during testing.

Features

• Pressure indication for leakage testing in different refrigerant systems
• Suitable for nitrogen charging, cleaning, and protection of welded piping
• Compact ball valve for easy and precise pressure control
• Available with various connector types to suit different customer requirements
• A red pointer can be used to record the input pressure
• Suitable for refrigeration and air conditioning system testing and servicing

The HONGSEN GBC Ball Valve is designed for air-conditioning and refrigeration systems where technicians need reliable refrigerant flow control. Its quarter-turn operation allows the valve to move quickly between fully open and fully closed positions.

The valve uses modified PTFE sealing, an explosion-proof valve stem design, and an argon arc welded structure for dependable service. It also supports two-direction flow and can be mounted on a control panel, making it suitable for different HVAC installation and service setups.

Features

• Full-flow design helps avoid pressure drop when the valve is open.
• Quarter-turn operation opens or closes the valve with a 90° turn.
• Turning stop prevents operation beyond the fully open or closed position.
• Open/close markings on top of the valve stem make its position easy to identify.
• Two-direction flow allows refrigerant flow in either direction.
• Argon arc welded structure for a secure valve body construction.
• Explosion-proof valve stem design for added operating safety.
• Modified PTFE sealing for reliable sealing performance.
• Internal liquid accumulation is avoided through the valve design.
• Control-panel mounting allows convenient installation in suitable systems.
