Valves & Pipes

 
The advantage of SP is a successful combination of metal and plastic together in one pipe. It is completely corrosion and scale resistant, both internally and externally. It can be used in a wide variety of installations and can be simply and easily bent by hand. SP pipes are acoustically and thermally insulated, can be located quickly by metal detectors and can be easily attached to any existing system. 
 
 
Any water line that might be exposed to freezing temperatures needs some type of freeze protection. Similarly, process equipment carrying water, such as pumps and valves, that may be subjected to freezing conditions should also be protected.

Automatic drain valves provide another solution to freeze protection of water lines that are exposed to intermittent freezing temperatures. This approach is simple and inexpensive. One or more Ogontz FPS-35 or FPS-40 freeze protection valves at appropriate points in the system provide the most economical way to protect water lines and other equipment from expensive freeze damage

Sagiv offers you brass hot forging and precision machining services, all under the same roof. A unique blend of skills, technologies and three decades of experience lead to superior results at every step of the process: design, development, production and assembly of complex brass components.

Thermostatic mixing valve for restricting water temperature ThermoGard is fitted between the hot water outlet pipe of solar water heaters and the home hot water piping system. Its purpose is to ensure that water temperature does not exceed 50 °C in order to avoid burns and damage to piping.
 
Apex Valves South Africa (Pty) Ltd was established in 1997 and started as a joint venture with Apex Valves New Zealand. It since became a whole South African owned company but retained its close relationship with Apex Valves New Zealand.  We manufacture a full range of valves suited for the highly competitive plumbing and geyser markets. All its products are SABS approved and JASWIC accepted. The fact that its products are locally manufactured assures excellent quality and technical support. Quick response to problem solving is guaranteed.  Due to local demand Apex SA recently added a range of safety valves to its already proven and established product range which makes it a leader in the supply of quality, affordable and guaranteed pressure control and safety valves.    Apex Valves has with great pleasure been servicing the market for the past 10 years

The Invensys FP-35 and FP-45 Freeze Protection Valves utilize a reliable self-contained Dole Power Element which is sensitive to temperature and operates without any electrical power or sensors. Typically in solar applications, the valve port opens on descending temperatures allowing the near freezing water in the solar panel to be discharged and replaced with warmer supply water. When the warmer water reaches the FP-35 or FP-45, the valve port closes and water discharge stops.

Design Features:
- Easily installed on existing systems.
- 1000kPa maximum operating pressure.
- Corrosion resistant design.
- FDA and NSF listed materials.
- LA testing and IAPMO listed.
- Anti-siphon and alternate discharge port.
- Discharge port for 1/4" plastic pipe or 5/8" ID hose.
- 1/2" brass male pipe thread inlet port for positive seal.
- Tamper resistant design.
- Nominal start to open temperature of FP-35 is
  3.3333ºC and FP-45 is 6.1111ºC.
- Completely mechanical operating principle.
- High temperature UV stabilized body material.
- Ideal for backup freeze protection
