One way valves are used for controlling the direction of flow of a fluid.

Design can include umbrella valves, duck bill valves and diaphragm valves.

One way valves can be designed to provide the customer’s required head loss and flow rate for particular applications.

A range of materials are available to handle different fluids and service conditions.


  • Cost effective method for controlling fluid flow in a compact design.
  • Gulf Rubber can design and manufacture one way valves to handle a wide range of fluids and service conditions.
  • One way valves can be designed to suit particular flow rate and head loss requirements.
    In house development and testing facilities.


  • One way valves can be manufactured in a wide range of elastomers, including natural rubber, SBR, NBR, EPDM, Silicone, Fluoroelastomer, Fluorosilicone, Polyurethane and Polyacrylate.
  • Materials available with international potable water approvals including WRAS, WRC, BS6920-UK, ACS France, KTW-Germany, AS4020-Australia and NZ, NSF 61-USA.
  • In house compound development to design materials to optimise performance in customer’s application.
  • In house testing of key compound properties for good long term performance such as stress relaxation, heat ageing, fluid ageing, ozone and chloramines resistance.
