{"product_id":"parker-watts-qix-pst20-porting-block-pressure-switch","title":"Parker Watts QIX PST20 Porting Block with 1908 Pressure Switch","description":"\u003cp\u003ePST20 is a QIX porting block with a Parker 1908 pressure switch already fitted to it. The switch closes an electrical contact once set pressure is reached, which is how a machine knows it has air before it starts a cycle, or how a panel light tells an operator the station is live. Branch lines off the block are 1\/4 in.

If your application depends on a specific switching pressure or contact rating, tell us what you need and we will get it confirmed by the manufacturer before the order ships rather than after.\u003c\/p\u003e\n\u003ch3\u003eInterlocks\u003c\/h3\u003e\n\u003cp\u003eA pressure switch at the FRL is a permissive, not a safety device. It tells a controller that air is present. It does not prove the lockout valve is open, it does not prove the downstream circuit is intact, and it should not be the only thing standing between an operator and a machine that moves. Use it for what it is good at.\u003c\/p\u003e","brand":"AirComParts","offers":[{"title":"Default Title","offer_id":68005233230099,"sku":"S6015","price":399.23,"currency_code":"USD","in_stock":true}],"url":"https:\/\/aircompressorstore.com\/products\/parker-watts-qix-pst20-porting-block-pressure-switch","provider":"Warthog Air Compressor Store","version":"1.0","type":"link"}
