{"product_id":"prv-m10-asm","title":"Pressure Relief Valve","description":"\u003cp\u003eThe Pressure Relief Valve is an important safety mechanism for our \u003ca href=\"\/products\/wte-locking-tube-r1-vp\"\u003elocking watertight enclosures\u003c\/a\u003e and also adds a few features to the enclosures.\u003c\/p\u003e\n\u003cp\u003eWhy is it needed for safety? Our watertight enclosures have come with a \u003ca href=\"\/products\/vent-asm-r1\"\u003emanual vent\u003c\/a\u003e that has worked great for years. But, our next generation watertight enclosures have a locking cord that secures the flange to the tube and prevents the end cap from coming off.\u003c\/p\u003e\n\u003cp\u003eIn the rare situation that an excessive amount of pressure builds up in the tube it can create an unsafe situation and\/or damage to the enclosure. Pressure build-up could be due to the buildup of gasses from a chemical reaction like something catching on fire, or from a slow leak into the enclosure while at depth followed by a quick return to the surface. The PRV automatically releases any excess pressure built up inside a watertight enclosure. It works automatically to relieve pressure, and it also works manually, like our original vent.\u003c\/p\u003e\n\u003cfigure\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1017\/5745\/2662\/files\/PRV-web-cross-section-2.png\" alt=\"\"\u003e\n\u003c\/figure\u003e\n\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/UmTLsIMAQuk?feature=oembed\" allowfullscreen\u003e\u003c\/iframe\u003e\n\u003cp\u003eThe PRV has an M10 thread so that it can be mounted to any of our watertight enclosure end caps.
