Perfect solution for precise flow throttling

The design of diaphragm valves allows them to be used in high-cycle applications without wear to their sealing surfaces. Because their open-to-close cycle is greater than 90 degrees, they can be used for more precise throttling than standard ball or butterfly valves. In the closed position, there is no entrapment of fluid within the valve body; this means that diaphragm valves are a good choice for volatile fluids that are off-gas or high purity applications where stagnation can lead to bacterial growth.

Diaphragm valves are available from 1/2” to 6” sizes in PVC, CPVC, ABS, PP, and PVDF and are the perfect solution when flow throttling is required, and dirty or volatile fluids are involved. The weir-style design — no dead space in the valve — is extremely good for abrasive slurries.

product overview

The VM Series Weir-Style Diaphragm Valves are available in PVC, CPVC, PP, or PVDF,  with four body styles, and three choices of diaphragms (EPDM, FPM, or PTFE). Able to be mounted in any position, the VM Series is ideal for either very clean or abrasive slurry applications. A unique and proprietary PTFE diaphragm design, available automation, and multiple accessories make this one of the most advanced and versatile lines in the industry. IPEX diaphragm valves can be pneumatically actuated providing precise control of critical applications.

This valve can be found in applications such as:

  • Aquarium Piping Systems
  • Metals & Mining
  • Shipbuilding and Offshore applications
  • Water and wastewater treatment

The CM Series Compact Diaphragm Valves have an efficient design and are ideal for OEMs. A variety of body and diaphragm materials plus the option of pneumatic actuation combine to make this valve the perfect choice for a wide range of applications.

specifications

  • Pressure: up to 90 psi at 73°F

features & benefits 

  • Precise flow control
  • High cycle life
  • Excellent for abrasive slurries
  • All bodies to be used with EPDM or Viton® diaphragms shall feature raised molded sealing rings (concentric), or with PTFE diaphragms shall be machined flat
  • All manual valves shall have a rising position indicator
  • Bodies of all sizes and materials shall have integral mounting brass inserts

product overview

The CM is a compact design with true union ends, available in PVC, CPVC, PP, or PVDF. With three diaphragm options (EPDM, FPM, or PTFE). These manually operated or pneumatically actuated valves are ideal for OEMs. The standard position indicator and integrated mounting bushings complete the long list of the CM Series Compact Diaphragm Valve features. These valves are a part of our complete systems of pipe, valves, and fittings, engineered and manufactured to our strict quality, performance, and dimensional standards.

They are widely used in high-purity applications because their design prevents friction and subsequent particle creation when cycling. All valves shall be weir-style for throttling applications. Many bodies and diaphragm material options are available as well as simple pneumatic actuation.

This valve can be found in applications such as:

  • Aquarium Piping Systems
  • Metals & Mining
  • Shipbuilding and Offshore applications
  • Water and wastewater treatment

The new DK series Dialock® diaphragm valves are available in PVC, CPVC, PP, or PVDF, with four body styles, and three choices of diaphragms (EPDM, FPM, or PTFE). They can be mounted in any position and it is an ideal solution for modulating flow in either very clean or abrasive slurry applications.

product overview

The new innovative and patented Dialock® locking mechanism allows the manual handwheel to be adjusted and locked in over 300 positions. The re-designed weir style body has significantly improved the DK’s flow rate compared to the other designs, and it facilitates precise linear flow regulation through the valve’s full range of operation. The new DK is available in manual and pneumatic control styles.

This valve can be found in applications such as:

  • Aquarium Piping Systems
  • Metals & Mining
  • Shipbuilding and Offshore applications
  • Water and wastewater treatment

The DKD Series diaphragm valve is an ultra-compact, direct acting pneumatic valve that is ideal for shutting off extremely dirty and highly viscous fluids.

Specifications

  • Size: 1/2” through 2”
  • Pressure:120 psi

featureS & BENEFITS

  • Compact Polypropylene Actuator for superior chemical resistance
  • EPDM liner Re-enforced with textile fibers
  • Improved weir design and optimized flow performance
  • Standard IPS connections
  • True Union design for ease of replacement. Spigot design is also available
  • The normally open design utilizes the line pressure to open the diaphragm and control pressure to close it. No spring required!
  • Threaded Stainless Steel insert for wall mount applications
  • Small body size and lightweight

product overview

The internal geometry of the body optimizes fluid dynamic efficiency by increasing the flow rate. The valve is comprised of three elements: the body, diaphragm, and sealing bonnet. When compressed air enters the bonnet, the diaphragm is pressed against the body’s weir, interrupting the flow. This simplified operating principle and the lower number of components guarantee high reliability and durability. The DKD Series Diaphragm Valves are part of our complete systems of pipe, valves, and fittings, engineered and manufactured to our strict quality, performance, and dimensional standards.

This valve can be found in applications such as:

  • Aquarium Piping Systems
  • Metals & Mining
  • Shipbuilding and Offshore applications
  • Water and wastewater treatment

Diaphragm valves are the perfect solution when precise flow throttling is required.

product overview

The DV Series Diaphragm Valve is a rugged industrial product ideal for throttling or use in abrasive slurry lines. The raising position indicator also functions as an adjustable travel stop. This feature can be used to avoid over-compression of the EPDM or PTFE diaphragm or as a travel limiter allowing different settings for the “closed” position. The molded flanged body eliminates potentially leaky joints while featuring end-to-end dimensions identical to most plastic-lined metal diaphragm valves, allowing for direct replacement.
