Safety Warning

Descripción completa del producto

Parker's Global P31D and P32D Global Dump Valves efficiently manage pressure by safely and quickly exhausting pneumatic energy in an industrial environment. These quick dump valves are high flow, normally closed, 3-port, 2-position directional control valves. Upon energizing the solenoid, inlet air is applied to the top of the piston. The piston pushes against the spring and opens the main valve providing full flow air to the downstream. When the solenoid is de-energized, the main valve closes allowing downstream air to exhaust rapidly through the bottom plug. The bottom plug is tapped so that exhaust may be piped away or fitted with a muffler/silencer. These global dump valves can be mounted using a modular connector to other P31/P32 Global Air Preparation products.

Parker P31S and P32S Global Soft Start Valves offer increased productivity by providing safe introduction of pressure to machines or systems and potentially reducing damage that can occur at start up. They allow the pressure to gradually build to a set point before fully opening to deliver full air line pressure. The controlled introduction of pressure can be an important safety factor and prevent damage to tooling when the air pressure is introduced at machine or system start up. When pressure is supplied to the inlet port, gradual filling of the downstream system occurs through the adjustment needle valve. The piston opens the main valve when the downstream side of the valve reaches approximately 60% of the supply pressure. The ramp up time to reach the switch-over pressure is adjustable via the needle valve in the cover. The P31S and P32S Global Soft Start Valves can be mounted using a modular connector to other P31 and P32 Global Air Preparation Products.

P31T and P32T Modular Global Combined Soft Start/Dump Valves provide for the safe introduction of pressure to machines or systems. Soft start/dump valves, when set, allow the pressure to gradually build to the set point, before fully opening, to deliver full flow air line pressure. The controlled introduction can be an important safety factor and prevent damage to tooling when air pressure is introduced at machine or system start up. When the valve is installed into the pneumatic system and the pilot operator receives no signal, the air is blocked at port 1. When a pilot signal is received at the pilot operator, the valve shifts, closing the connection between ports 2 and 3. At the same time, air flow begins between ports 1 and 2 at a slow rate, controlled by the needle valve located on top of the valve. When the downstream pressure reaches approximately 60% of the supply pressure, the main valve spool opens, allowing full flow through the valve in the system. If pilot signal or system pressure is lost, the valve returns to its initial state, venting the downstream pressure through port 3.

Pressure supply piping must be the same size as the inlet port or larger, to ensure the pilot valve receives sufficient pressure supply during high flow conditions. The valve should be mounted downstream of the FRL, with the soft start adjustment needle easily accessible. The P31T and P32T Global Soft Start/Dump Valves can be mounted using a modular connector to other P31 and P32 Global Air Preparation Products. Note: soft start/dump valves are not intended to be used as emergency shut-off valves, but should be placed after a manual shut off valve.
