Always check the chemical compatibility of EPDM with your specific fluid and operating temperature before selection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan these valves be installed in any orientation within the pipeline?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn most cases, PVCu diaphragm valves can be installed in horizontal or vertical pipe runs, but best practice is to follow the flow direction indicated on the valve body if present, and to ensure the handwheel is accessible for operation and maintenance. Avoid mounting in positions where debris may accumulate around the diaphragm, and always support the pipework correctly to prevent undue stress on the valve.\u003c\/p\u003e","brand":"Plastock","offers":[{"title":"20mm","offer_id":56199265255804,"sku":"PLT_PLC10260","price":260.14,"currency_code":"GBP","in_stock":true},{"title":"25mm","offer_id":56199265288572,"sku":"PLT_PLC10261","price":290.78,"currency_code":"GBP","in_stock":true},{"title":"32mm","offer_id":56199265321340,"sku":"PLT_PLC10262","price":355.4,"currency_code":"GBP","in_stock":true},{"title":"40mm","offer_id":56199265354108,"sku":"PLT_PLC10263","price":468.78,"currency_code":"GBP","in_stock":true},{"title":"50mm","offer_id":56199265386876,"sku":"PLT_PLC10264","price":603.44,"currency_code":"GBP","in_stock":true},{"title":"63mm","offer_id":56199265419644,"sku":"PLT_PLC10265","price":723.08,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/9262\/2987\/files\/f3217a09d2a4136bc4ac0091561d9de2.png?v=1767776084","url":"https:\/\/plasticsco.co.uk\/products\/premium-pvcu-diaphragm-valve","provider":"Plastics Co Uk","version":"1.0","type":"link"}
